PREFACE
This document contains a listing of the TOPS-20 BUGINFs, BUGCHKs, and
BUGHLTs, and gives an explanation of most of the error conditions.
The list is in alphabetical order according to the name of the BUG.
Every system bug is defined by the macro BUG.. The definition of each
BUG. has multiple parts. Below is an example of a BUG. definition.
BUG.(CHK,DNDXMF,DNADLL,SOFT,<Transmit message to Ethernet failed>,
<<T1,ERRCOD>>,<
Cause: NISRV returned an error when trying to queue a message
for transmit.
Action: Check the error code in T1 and correct the problem in
NISRV.
Data: ERRCOD - Error code returned by NISRV.
>,FREUNB)
An explanation of the parts of this BUG. definition follows:
1. The BUG. line or lines contains the following information:
o The word BUG. defines the beginning of the BUGINF,
BUGCHK, or BUGHLT macro. Everything within the
parentheses that follows is the definition of the BUG.
macro.
o The string CHK means that this BUG. is a BUGCHK. If
this string is INF, the BUG. is a BUGINF. If this
string is HLT, the BUG. is a BUGHLT.
o The string DNDXMF is the name of the BUGCHK.
o The string DNADLL is the name of the monitor module that
contains the BUG..
o The word SOFT indicates that this is most likely a
software problem. The word HARD in place of the word
SOFT indicates a possible hardware problem. It is also
possible that a SOFT error can be caused by a hardware
failure, and that a HARD error can be caused by a
software failure.
o The string <Transmit message to Ethernet failed> is the
message that is printed on the CTY when this BUGCHK
occurs. The angle brackets (<>) delimit this message.
Page 4
o The string <<T1,ERRCOD>> contains the data associated
with this BUGCHK. Note that the names of the data are
provided in the BUG. lines, but are not printed on the
console terminal when the BUG. occurs. The data varies
from BUG. to BUG.. Often no data is pertinent and no
data items are provided.
2. Cause: This section gives a description of what caused this
BUG.. If no cause section is provided, this BUG. has no
documentation except the message that appears on the BUG.
line.
3. Action: This section describes the corrective action you can
take. If the BUG. is a BUGHLT and there is no action
section, please submit a Software Performance Report (SPR)
with a crash dump and an unrun copy of your monitor.
4. Data: This section describes the data given in the BUG.
line. This is an optional section.
5. FREUNB This string names the routine that is called to clean
up after an error. It is an optional string.
BUG.(HLT,ABKSKD,PAGEM,SOFT,<Address break from scheduler context>,,<
Cause: A page failure occurred while the monitor was running in scheduler
context, and the page fail word indicated an address break. Address
breaks can only be set in code that runs in process context.
>)
BUG.(HLT,AGSETX,PAGEM,SOFT,<AGESET - XB needs checking>,,<
Cause: A index block that has been "forced out" needs to be swapped in and
checked.
>)
BUG.(CHK,ANIOPF,IMPANX,HARD,<IO page fail from AN20>,<<P1,NCT>>,<
Cause: The AN20 was found to be the cause of an IO Page Fail.
This means that the hardware got a page fault during an interrupt
instruction. This may indicate a hardware problem with the AN20.
>)
BUG.(HLT,APRAPE,APRSRV,HARD,<Address parity error>,,<
Cause: An APR interrupt occurred because a memory controller
signaled that it received an address with even parity
from the processor. There is a description of the problem
on the CTY.
Action: Using SBUS diag 0 for all memory controllers, check the
address parity error bit(s). Test the bus and controller.
>)
BUG.(HLT,APRNX1,APRSRV,HARD,<NXM detected by APR>,,<
Cause: An APR interrupt occurred because the processor attempted to
access a memory that did not respond within a preset time. This
can indicate broken hardware or a software bug. The monitor
has printed a description of the problem on the CTY.
Action: The analysis of this BUGHLT is extremely complicated.
The physical address from the error register is printed on the
CTY ("ERA="). If there is physical memory at this address, the
problem is probably in the hardware. If the address does not
exist, the problem may be in either hardware or software.
One software problem that has led to this BUGHLT in the past
is code that returns an SPT slot to the free pool while leaving
a pointer to that slot in some page table. The content of
the SPT entry, instead of being a pointer to memory, is a
pointer to another SPT slot.
In this case, a page fault will have occurred just before the
interrupt. The PC will point into the page fault handler. The page
fault word and PC (TRAPSW and TRAPPC, respectively) will
indicate the virtual address and instruction at the time of
the page fault. Tracing this virtual address to the SPT will
produce the erroneous SPT entry.
Note, however, that this BUGHLT is rarely caused by software
in the field. The hardware is probably broken.
>)
BUG.(HLT,APRNX2,APRSRV,HARD,<NXM detected by APR>,,<
Cause: A page fault occurred, indicating that the processor
attempted to access a memory that did not respond within
a preset time. The monitor is presently processing an
interrupt or running in the scheduler and the interrupt
system is turned on. Since non-existent memory also
produces an APR interrupt, which results in an APRNX1 BUGHLT,
this BUGHLT does not normally occur.
Action: See APRNX1. Note, however, that the occurrence of this BUGHLT
instead of APRNX1 may indicate a failure in the interrupt
system.
>)
BUG.(CHK,ARCASS,JSYSF,HARD,<ARCF - File directory and mapped directory do
not match>,,<
Cause: The directory number of the currently mapped directory does not
match the directory number of file that we are attempting to set
tape information for in a ARCF% .ARRST request.
>)
BUG.(CHK,ARCVER,IPCF,HARD,<ARCMSG - NOUT failed>,,<
Cause: ARCMSG attempted to NOUT the generation number of a file and it
failed.
>)
BUG.(HLT,ARSTXX,JSYSF,SOFT,<ARRST - FDB disappeared for destination file>,,<
Cause: The FDB for a file being restored from offline does not exist.
>)
BUG.(CHK,ASAASG,DSKALC,SOFT,<DSKASA - Assigning already assigned disk address>,
<<T1,STRCOD>,<T2,SECTOR>>,<
Cause: The sector being assigned on the disk is already assigned.
This may happen during creation of structure when assigning
swapping space, and the sector is already assigned in the
BAT blocks.
Data: STRCOD - Structure Unique Code
SECTOR - Sector Number on Disk Relative to Start of Structure
>)
BUG.(CHK,ASGBAD,DSKALC,SOFT,<DSKASA - Assigning bad disk address>,
<<T3,STRCOD>,<T2,SECTOR>>,<
Cause: The sector being assigned was not within the legal range
of sector numbers.
Data: STRCOD - Structure Unique Code
SECTOR - Sector Number on Disk Relative to Start of Structure
>)
BUG.(CHK,ASGBPG,DSKALC,SOFT,<INIBTB - Failed to assign bad page(s)>,
<<T1,STRCOD>,<T2,AMOUNT>>,<
Cause: The bit table is being initialized; home blocks, pages
in the BAT blocks, and swapping space are being assigned.
Address(es) in the BAT blocks were not assigned.
Data: STRCOD - Structure unique code
AMOUNT - Number of addresses not assigned
>)
BUG.(HLT,ASGFR0,FREE,SOFT,<ASGFRE - Illegal to assign 0 free space>,,<
Cause: An illegal request for free space is being made. The calling routine
is asking for zero words of free space.
Action: Look at the dump. By backing up the stack you
should be able to tell what routine called for the illegal
free space.
>)
BUG.(CHK,ASGINT,FREE,SOFT,<ASGFRE called OKINT>,<<C,CALLER>>,<
Cause: This is a free space problem. Calls to swapable free space
routines should be made only while the calling process is NOINT. The
calling routine is not protecting itself from losing free space. It is
OKINT. Since it is OKINT it could get interupted and never return,
thus losing the free block assigned.
Action: Make the routine be NOINT until it has ensured that the block will
be freed when it is interrupted (e.g. JSB stack).
Data: CALLER - The address of the calling routine
>)
BUG.(CHK,ASGREP,FREE,SOFT,<Illegal priority given to ASGRES>,,<
Cause: This is a free space problem. The caller is asking for resident
free space. In T3 the caller gives a priority for this request.
The priority determines how ASGRES is going to handle this request
when free space is low. This priority is out of range.
Action: If the problem persists change the BUGCHK to a BUGHLT and look
through the dump to find the caller.
>)
BUG.(CHK,ASGREQ,FREE,SOFT,<Illegal pool number given to ASGRES>,,<
Cause: This is a free space problem. The caller is requesting resident
free space. In T2 the caller is providing a pool number for where
the free space should come from. This pool number is incorrect.
Action: If the problem persists change the BUGCHK to a BUGHLT to find the
culprit. The caller putting a bad value into T2.
>)
BUG.(HLT,ASGSW2,PAGEM,SOFT,<SWPOMG - Cannot assign reserved drum address>,,<
Cause: The monitor is swapping a group of pages to a set of contiguous
pages in the swapping space. The swapping space manager has
provided a starting address for a block of free pages. An attempt
to assign one of the pages has failed. This indicates an
inconsistency in the monitor's data or a race condition.
For example, a context switch may have occurred when it was
not expected.
>)
BUG.(CHK,ASGSWB,SWPALC,SOFT,<SWPINI - Cannot assign bad address>,,<
Cause: Cannot assign bad drum address because it is an illegal
address or already assigned.
>)
BUG.(HLT,ASOFNF,DISC,SOFT,<DELFIL - ASGOFN gave fail return for long file XB>,,<
Cause: A long file was being deleted and ASGOFN could not assign a system file
number (OFN). This usually happens because there were not enough OFN
slots.
Action: If this happens frequently, rebuild the monitor with more OFN slots.
>)
BUG.(HLT,ASTJFN,LOOKUP,SOFT,<GETFDB - Called for JFN with output stars>,,<
Cause: The monitor tried to get a pointer to the FDB of an output file, and
the file specification used as an argument to GTJFN contains
asterisks.
>)
BUG.(CHK,BADADR,MNETDV,SOFT,<No NCT for address>,<<T1,ADR>>,<
Cause: The multinet output queuing mechanism was called for a local
address that has not been defined.
>)
BUG.(CHK,BADBAK,FILINI,HARD,<FILIN2 - Backup copy of ROOT DIRECTORY is not
good>,,<
Cause: The backup copy of the root directory is bad.
Action: Re-create the backup copy of the root directory.
>)
BUG.(CHK,BADBAT,DSKALC,HARD,<BAT blocks unreadable>,,<
Cause: BAT block header contains bad information.
>)
BUG.(HLT,BADBUF,MNETDV,SOFT,<Null buffer address>,,<
Cause: Multinet has been called to queue an output buffer with a null
address.
>)
BUG.(HLT,BADDAC,DIRECT,SOFT,<INSACT - Null account string seen>,,<
Cause: A null account string was given for insertion into the FDB by the
monitor during the creation of a file or while executing a SACTF JSYS.
>)
BUG.(HLT,BADFEV,PHYSIO,SOFT,<CHKPDB - Wrong or bad front-end version>,,<
Cause: The front-end did not send a type 40 message to idenify the
front-end disk serial numbers.
Action: Fix the front-end.
>)
BUG.(CHK,BADIDX,FILINI,HARD,<IDXINI - Partially unsuccessful index table
rebuild>,,<
Cause: IDXINI failed to create the index-table file during a refresh of
PS:. Some of the directories may have been entered into the file
before this failure occurred.
>)
BUG.(HLT,BADIRB,PHYSIO,SOFT,<Bad IORB passed to GIVIRB>,,<
Cause: An IORB was passed to GIVIRB that does not have a legal address.
This indicates a software problem in the monitor.
>)
BUG.(HLT,BADPTR,PAGEM,SOFT,<Bad section pointer - SECMAP>,,<
Cause: The section pointer being deleted was not one of the
types (share or indirect) expected.
>)
BUG.(HLT,BADREC,FILINI,hard,<FILINI - Reconstruction of ROOT-DIRECTORY
failed>,,<
Cause: One of the following failures occurred during attempted reconstruction
of the root directory during system startup: could not
get OFN for backup root-directory; could not get OFN for the root-
directory; could not assign a page in the job data area to build the
backup index block; or the backup root-directory is clobbered.
>)
BUG.(HLT,BADROT,FILINI,HARD,<FILIN2 - ROOT-DIRECTORY is invalid>,,<
Cause: When the system was coming up, BLKSCN was called to check the
consistency of the root directory. This error means that
BLKSCN found that the root directory had an unrecognizable type,
the last block did not have the expected length, or some block
had an incorrect format.
Action: Use EDDT to break after BLKSCN and examine the error code in AC1.
This code will sometimes indicate what is wrong with the root
directory. If other BUGCHKs or BUGINFs occur with this BUGHLT, they
also can provide helpful information.
If the system can be brought up using another structure as PS:,
the bad structure can sometimes be fixed with various tools such
as FILDDT. If this restoration fails, the pack can be started
afresh and pertinent DUMPER backup tapes can be used to restore the
structure.
>)
BUG.(CHK,BADTAB,JSYSA,HARD,<VERACT - Spurious hash table encountered>,,<
Cause: This BUG indicates that a block has been found in the monitor's
account data base that is not an account block. The account data
base is corrupted.
>)
BUG.(HLT,BADTTY,TTYSRV,SOFT,<Transfer to nonexistent TTY code>,,<
Cause: The transfer vector for a non-existent TTY line type was
referenced.
Action: Look at the dump. The stack should indicate which routine caused
the reference.
>)
BUG.(HLT,BADTYP,TAPE,HARD,<Bad label field desc>,,<
Cause: This is a bug in TAPE. The internal routines in TAPE have a table
with codes that describe the type of data in particular label fields
(octal,string,decimal). One of these tables has a code that is
out of range.
Action: Try to find out where the out of-range-code came from.
>)
BUG.(HLT,BADXT1,FILINI,SOFT,<Index table missing and can not be created>,,<
Cause: During system startup, MAKIDX failed to recreate the index
table file. This will occur, for instance, if one of the following
conditions exist: ASGJFR fails to get free space, STRST fails to create
a filespec; GTJFN fails to create the file; OPENF fails to open it.
>)
BUG.(CHK,BADXT2,FILINI,HARD,<Index table missing and was created>,,<
Cause: During system startup, FNDIDX failed to get an OFN for the index
table file so MAKIDX has been called to create a new one.
>)
BUG.(HLT,BADXTB,FILINI,SOFT,<FILIN2 - Could not initialize index table>,,<
Cause: This can happen either because IDXINI failed during normal
system startup, or because MAKIDX failed during a special startup
while PS: was being created.
>)
BUG.(HLT,BKUPDF,PAGEM,SOFT,<BKUPD - Bad CST1 entry or inconsistent CST>,,<
Cause: A routine has been called to swap a core page to disk or drum.
It has decided to swap to the disk. The BUGHLT indicates that
no back address was found in the CST. This usually indicates
bad data in the CST or a bad pointer in a page table.
>)
BUG.(CHK,BLKF1,IO,HARD,<BYTINA - BLKF set before calling service routine>,,<
Cause: This is a consistency check in BYTINX. The environment is in IO where
sequential input is being processed. The code is getting ready to
jump to the device dependant code. Before doing so it sees if a bit
(BLKF) is set in STS (AC 8). This bit indicates that the service
routine wants to block. Therefore, no matter what the device
dependent routines do, the process will ultimately block. It is
unlikely that this is being done on purpose. It is more likely that
somewhere BLKF is not being cleaned up properly.
Action: If this is becoming a problem change the BUGCHK to a BUGHLT and
look at the dump.If FILSTS for the current JFN has the bit on then
the problem gets a little tricky since the previous use of it left
BLKF on. If BLKF is off in FILSTS then somewhere past the call to
CHKJFN it is being turned on.
>)
BUG.(CHK,BLKF2,IO,HARD,<BYTOUA - BLKF set before call to service routine>,,<
Cause: This is a consistency check in BYTOUA. The environment is in IO just
before it gets ready to call the device dependent routines to do output.
Bit BLKF in STS (AC 8) is on. It should be off. It causes the process
to block. It is unlikely that this sort of knowledge is available.
It is more likely that this is an error.
Action: If the problem persists change the BUGCHK to a BUGHLT and look at
the dump. If FILSTS for the current JFN has the BLKF bit on then
the last one to user the JFN left it in that state. A hard problem
to find. If BLKF is off in FILSTS then somewhere after the call to
CHKJFN the bit is being set on not reset.
>)
BUG.(CHK,BLKF3,JSYSF,HARD,<CLZDO - BLKF set before call to service routine>,,<
Cause: BLKF has been set before the call to the device dependent service
routine which should be responsible for setting this bit.
Action: If this BUGCHK persists, change it to a BUGHLT and find out where
the bit is being set.
>)
BUG.(CHK,BLKF4,JSYSF,HARD,<.GDSTS - BLKF set before call to device routine>,,<
Cause: The bit indicating that a device routine wishes to block has been
set before the call to the device routine has been made. This bit
must be set to zero before the call so we do not block needlessly
(maybe never to wake up).
Action: The bit is being cleared. If this problem persists, change the
BUGCHK to a BUGHLT and find out where BLKF is being set.
>)
BUG.(CHK,BLKF5,JSYSF,HARD,<.MTOPR - BLKF set before call to device routine>,,<
Cause: The bit indicating that a device routine wishes to block has been
set before the call to the device routine has been made. This bit
must be set to zero before the call so we do not block needlessly
(maybe never to wake up).
Action: The bit is being cleared. If this problem persists, change the
BUGCHK to a BUGHLT and find out where BLKF is being set.
>)
BUG.(CHK,BLKF6,JSYSF,HARD,<.SDSTS - BLKF set before call to device routine>,,<
Cause: The bit indicating that a device routine wishes to block has been
set before the call to the device routine has been made. This bit
must be set to zero before the call so we do not block needlessly
(maybe never to wake up).
Action: The bit is being cleared. If this problem persists, change the
BUGCHK to a BUGHLT and find out where BLKF is being set.
>)
BUG.(INF,BREAKIN,JSYSA,SOFT,<Password guess threshold exceeded>,
<<T1,CTRLTT>,<T2,USERNO>,<T3,STRNAM>,<T4,DIRNUM>>,<
Cause: Someone has typed more than MXFLCT incorrect passwords. The system
now refuses all subsequent passwords for some time. It is possible
the person is trying to guess passwords
Data: CTRLTT - The line number of the job
USERNO - The user number if the job is logged in
STRNAM - The sixbit name of the structure of the target
DIRNUM - The directory number of the target
>)
BUG.(HLT,BTBCR1,FILINI,SOFT,<FILINI - No bit table file and unable to
create one>,,<
Cause: MNTBTB failed, so the system restart logic called CRTBTB to
create a new bit table. CRTBTB failed too, so the BTBCR1 BUGHLT
happened. CRTBTB will fail if INIBTB fails. This can happen if
DSKASA fails to assign a disk page, or if SWPASN fails to assign
swapping space.
>)
BUG.(HLT,BTBCRT,FILINI,SOFT,<FILINI - Could not initialize bit table for
public structure>,,<
Cause: During special system startup in which PS: was being refreshed,
CRTBTB failed to build a new bit table. See CRTBT1 for more detail
on why CRTBTB fails.
>)
BUG.(INF,CCBROT,DIRECT,HARD,<CPYBAK - Can't copy backup root-directory>,
<<T1,LSTERR>>,<
Cause: The monitor has detected a problem with the backup root-directory
and is attempting to copy the primary root-directory to the backup.
The copy failed.
Data: LSTERR - Error returned from CPYBAK
>,R)
BUG.(HLT,CDILVT,CDRSRV,HARD,<Illegal device function code>,,<
Cause: In CDRSRV an illegal function code was specified. The
function codes allow for opening, closing, reseting, etc. A code
was specified that is out of range.
Action: Use the stack to find the routine that is specifying the wrong code.
The code is usually specified as the address field of a CALL
instruction.
>)
BUG.(HLT,CFACCF,CFSSRV,SOFT,<CFSSRV - SC.ACC failed>,
<<T2,NODE>,<T1,CID>,<T3,ERR>>,<
Cause: The call to SC.ACC failed.
Data: NODE - Node Number
CID - Connect ID
ERR - Error returned by SC.ACC
>)
BUG.(HLT,CFANAE,CFSSRV,SOFT,<CFSSRV - No allocation entry>,,<
Cause: The caller wanted to update a directory allocation entry, and
no such entry could be found
>)
BUG.(HLT,CFBAFN,CFSSRV,SOFT,<CFSSRV - Bad function to CFSDAU>,,<
Cause: CFSDAU was called with an invalid function.
Action: Find the caller in the dump and try to determine why it passed a
bad function code to CFSDAU.
>)
BUG.(CHK,CFCCLZ,CFSSRV,SOFT,<CFSSRV - Can't close CFS connection>,
<<T2,NODE>,<T1,CID>,<T3,ERROR>>,<
Cause: A "set CI offline" has been requested and SCA refuses to close
a CFS connection. The call to SC.DIS to disconnect from the remote
node failed. This may result in a CFRECN BUGHLT when the CI is put
on-line.
Data: NODE - node number of remote
CID - connect ID
ERROR - error code returned by SCA
>)
BUG.(INF,CFCCML,CFSSRV,SOFT,<CFSSRV - Cluster cease message lost>,,<
Cause: Another system sent a "cluster cease" that could not be queued
because there was no available resident free space.
>)
BUG.(INF,CFCONN,CFSSRV,SOFT,<CFSSRV - CFS connection>,
<<T2,NODE>,<T1,CID>,<T3,SERNUM>>,<
Cause: A CFS connection has been received from another node on the CI-20.
Data: NODE - Number of connecting node
CID - Connect ID
SERNUM - Serial number of remote node
>)
BUG.(INF,CFDISC,CFSSRV,SOFT,<CFSSRV - CFS disconnect>,
<<T2,NODE>,<T1,CID>,<T3,SERNUM>>,<
Cause: A CFS disconnect request has been received from a remote node on
the CI-20.
Data: NODE - Remote node number
CID - Connect ID
SERNUM - Serial number of remote node
>)
BUG.(HLT,CFGARD,CFSSRV,SOFT,<CFSSRV - Vote packet address is bad>,,<
Cause: A bad vote packet address has been given to CFSWDN.
>)
BUG.(HLT,CFLISF,CFSSRV,SOFT,<CFSSRV - SC.LIS failed>,<<T1,ERR>>,<
Cause: The call to SC.LIS failed.
Data: ERR - Error code returned by SC.LIS
>)
BUG.(HLT,CFNLTK,CFSSRV,SOFT,<CFSSRV - Null disk address given to CFSAWT>,,<
Cause: A call was made to create an OFN access token but SPTH for the
OFN is not set up.
>)
BUG.(HLT,CFRECN,CFSSRV,SOFT,<CFSSRV - Illegal reconnect>,<<T2,NODE>,<T1,CID>>,<
Cause: The VC between this system and another has been continued illegally.
Data: NODE - Number that has re-established a connection
CID - Connect ID
>)
BUG.(HLT,CFSBTP,CFSSRV,SOFT,<CFSSRV - Bad token packet>,,<
Cause: CFSAWT has been called to acquire an access token for an OFN.
The OFN access token already exists on this system and the
block address is in CFSOFN. But the OFN recorded in the
block does not match the one passed into CFSAWT.
>)
BUG.(HLT,CFSICN,CFSSRV,SOFT,<CFSSRV - Illegal configuration>,,<
Cause: This system has detected an illegal configuration. There may be
too many nodes in the network. The caller of this routine should
be examined for more details.
>)
BUG.(HLT,CFSIGT,CFSSRV,SOFT,<CFSSRV - Illegal return from CFSGET>,,<
Cause: A call to CFSGET, CFSGTT or CFSGTL returns +1 even though a
wait-until-successful was requested.
>)
BUG.(CHK,CFSILJ,CFSSRV,SOFT,<CFSSRV - Illegal Local Job Number>,,<
Cause: LCL2GL as been called to convert a local job number to a global
index, but the local job number is invalid.
Action: If this problem persists, change the CHK to a HLT and determine why
the caller is passing a bad job number.
>)
BUG.(HLT,CFSKPD,CFSSRV,HARD,<CFSSRV - The KLIPA failed>,,<
Cause: The KLIPA hardware or the CI has failed and CFS cannot continue.
>)
BUG.(HLT,CFSMPB,CFSSRV,SOFT,<CFSSRV - CFSMAP returned in-use entry>,,<
Cause: CFSMAP has returned a resource block that is already in use. This
bug is a debugging check.
>)
BUG.(HLT,CFSNAF,CFSSRV,SOFT,<Allocation entry not found>,,<
Cause: An allocation entry has just been created and CFSSRV can't find
it in the hash table.
>)
BUG.(HLT,CFSNOT,CFSSRV,SOFT,<CFSSRV - OFN token table and hash table
disagree>,,<
Cause: CFSSRV is trying to remove a file access token and has found the
token in the hash table but not in the OFN token table. This indicates
that one of the data bases is incorrect.
>)
BUG.(HLT,CFSOFB,CFSSRV,SOFT,<CFSSRV - OFN owned at CFSOFC>,,<
Cause: CFS has received a message from a remote system that an OFN
has changed and needs to be verified again. But CFS has found
that it owns the OFN. It should never have received such a
message.
>)
BUG.(HLT,CFSRNM,CFSSRV,SOFT,<CFRDSN - Could not rename DSN entry>,,<
Cause: A pack of a mounted structure has been moved to a new unit and
the new CFS mount resource already exists for the new drive.
Or, a drive on which there is a pack of a mounted structure has
been given a new drive serial number and the new CFS mount
resource already exists for the new drive.
This indicates either the CFS data base is wrong, or PHYSIO's
data base is wrong.
>)
BUG.(HLT,CFSSEZ,CFSSRV,SOFT,<CFSSRV - Section 0>,,<
Cause: HSHLOK was called from section zero. HSHLOK must be called from a
non-zero section.
Action: Examine the stack and change the caller of HSHLOK to run in a
non-zero section
>)
BUG.(HLT,CFSSUF,CFSSRV,SOFT,<CFSSUG - Could not find entry to upgrade>,,<
Cause: A request was made to change the mount type of a structure, and the
CFS data base has no record of the structure being mounted.
>)
BUG.(HLT,CFSTND,CFSSRV,SOFT,<CFSSRV - Access token not deleted>,,<
Cause: CFSCON was called to verify that an access token has been deleted
before an OFN is released. This BUGHLT indicates that the token has
not been deleted.
>)
BUG.(HLT,CFSTUC,CFSSRV,SOFT,<CFSSRV - Unexpected error encountered during
structure operation>,<<T2,CODE>>,<
Cause: A structure mount or dismount failed and generated an unexpected or
illegal error code. If the error code is -1 then the failure was
local to this system. This should not happen for structures.
Also, there should never be an error code of zero.
Data: CODE - Bogus error code
>)
BUG.(HLT,CFSVFL,CFSSRV,SOFT,<CFSSRV - Structure verify failed>,,<
Cause: CFS could not verify an existing structure resource during
the join operation. This probably means there is a structure

word contains the length of the block in the right half, and a "check"
quantity in the left to verify that this block is what is expected.
This bug means that this word has either been trashed, or the
pointer we have been passed is bad.

or if the check word is 63D. If the check word is 63D the memory has
already been returned and we are trying to return it again. If the
check word is trashed then possible the owner trashed it or the user
of the memory block previous to this one wrote too far. If FTD36MM=0
then the owner of the memory block is recorded in the block's header.

that more sectors must be read to complete the transfer. However,
the RP20 is formatted in pages and no transfer is ever longer than
a page, so the skip return should never occur.

BUG.(HLT,FILBTB,FILINI,SOFT,<Unable to write bit table file>,,<
Cause: This BUGHLT will occur when FILRFS is refreshing PS:.
FILRFS calls WRTBTB to write the bit table, and WRTBTB fails
for a reason other than MSTRX6 (home blocks are bad). WRTBTB
will fail for several reasons including: GETBTB failed to get
a JFN on the bit table file: the OPENF failed: CHFDB, GTFDB, or
MODHOM failed.
Action: Use EDDT to specifically determine what is failing.
>)
BUG.(CHK,FILCCD,FILINI,HARD,<Could not create directory>,,<
Cause: FILCRD failed to create one of the standard system directories
during a PS: refresh because STRST failed to form a complete

code from the structure number or if a DEVST fails to convert the
structure number to a string.

BUG.(CHK,FILFEF,FILINI,HARD,<Could not create front end file system>,,<
Cause: FEFSYS failed to create a front end file system. FEFSYS will fail
for several reasons. For example, ASGPAG can fail or the count of
front end pages in the home blocks can be negative.
Action: Rebuild the front end file system by hand.
>)
BUG.(CHK,FILHOM,FILINI,HARD,<Unable to rewrite home blocks in WRTBTB>,,<
Cause: FILRFS is attempting to refresh PS:. WRTBTB is called to write the

Cause: This will occur during special system startup if FILRFS,
while trying to build PS:, gets a failure return from DIRINI, which
is trying to initialize the root directory. DIRINI will fail if its
call to MAPDIR fails, or if the SETZM which first touches the directory
fails. MAPDIR will fail if either the structure or directory number
is out of range, or if MAPIDX fails to map in the index table.
Action: Use EDDT to determine exactly what is failing and why.
>)
BUG.(CHK,FILJB1,FILINI,HARD,<FILCRD - No room to create standard system

Cause: FILCRD could not create the standard system directories during a
refresh of PS: because it could not get JSB free space for use
during CRDIR calls.
>)
BUG.(HLT,FILMAP,FILINI,SOFT,<FILIN2 - Could not map in ROOT-DIRECTORY>,,<
Cause: During standard system startup, SETDIR failed to map in the
root directory for consistency checking. SETDIR will fail if CNVSTR
fails to convert structure number data or if MAPDIR fails to map in
the directory, or if DR0CHK finds a directory header inconsistency.
Action: Use EDDT to figure out exactly which reason is the cause.
>)
BUG.(HLT,FILRID,FILINI,SOFT,<FILINW - Index table already set up for root

Cause: This BUGHLT will occur if, during a refresh in the FILRFS routine
during system startup, the SETIDX call fails. That call is trying to
set up the index table for the root directory for PS:. SETIDX fails if
it is passed a directory number that is out of range, or if the index
table is already set up but at a different spot than that requested in
the current call.

<<JOBNO,JOB>,<FORKN,JBFORK>>,<
Cause: The FLOCK routine has encountered the nest count for the fork lock
being non-zero, which should not be, since the lock has just been
locked for the first time. This is probably due to some other
software not having cleared the nest count from some previous lock.
Data: JOB - Internal Job number whose fork discovered the non-zero

BUG.(INF,FLKINT,FORK,SOFT,<FLOCK - Called while NOINT>,,<
Cause: The routine FLOCK was called while the calling process was
unable to be interrupted. The calling fork was not nesting the lock
nor was it the top fork of the job. This indicated a logic error
because if this fork was unable to aquire the lock it will DISMS
while NOINT. This can cause a deadly embrace where the fork which
owns the lock will not relenquish it until the fork which has dismissed
is interrupted which will never happen because the fork is NOINT.
Action: Change this into a BUGHLT and look at the resulting dump. This will
allow you to find the erroneous routine.
>)
BUG.(CHK,FLKNS,FORK,SOFT,<FUNLK - Lock not set>,<<FORKN,JOBFRK>>,<
Cause: The FUNLK routine, which unlocks the fork lock, detected that the
lock was already unlocked. This should not be, since anyone

Cause: A fork has been waiting a "long time" for the fork lock.
This bugchk announces that the system is assuming that some fork has
neglected to unlock the fork lock and the waiting fork is being
given the lock even though someone else still has it.
The code could be in error here. The measure of a "long time" is
calculated arbitrarily and can be changed. It is parameter FLKTMV.

an analysis of the error on the CTY, and A SYSERR entry will be
created when the monitor is rebooted.

BUG.(HLT,FSPANN,FREE,SOFT,<ASGFRE called OKINT>,<<T4,POOLN>,<T3,CALRPC>>,<
Cause: This is a free space problem. Calls to swapable free space
routines should be made only while the calling process is NOINT. The
calling routine is not protecting itself from losing free space. It is
OKINT. Since it is OKINT it could get interrupted and never return,
thus losing the free block assigned.
Action: The data supplied gives the address of the calling routine. Make
the routine NOINT until it has insured that the block will be
freed when it is interrupted (e.g. JSB stack).

BUG.(HLT,FSPARB,FREE,SOFT,<RELFSP - Bad block being released>,
<<Q1,POOLN>,<T4,CALRPC>,<P2,BLKADR>>,<
Cause: The caller is attempting to release a block that has already been
released.
Action: If the problem persists, change the BUGCHK to a BUGHLT. Looking at
the stack will show the caller. It is possible that the length of the
current block is incorrect. It is equally likely that the
block(s) before this block (in free space) have had incorrect
lengths on return. Thus, the caller may not be the culprit.
Data: POOLN - Pool number
CALRPC - PC of caller of RELFSP
BLKADR - Address of user block

BUG.(HLT,FSPBBS,FREE,SOFT,<Bad blocksize>,<<P1,POOLN>,<P2,BLKADR>>,<
Cause: This is a free space problem; The block size is either smaller
than the minimum block size for this pool, or larger than the entire
amount of space allocated to the pool.
Action: If the condition is noticed when a block is being returned to the list,
it is simply marked deassigned (and bad) but not returned to the list.
If the list header is large enough to include it, the PC, job
number and fork number of the assigner and deassigner are stored in
the header/trailer. These may give a clue as to what code caused the
problem.
If the problem persists, change the BUGCHK to a BUGHLT and analyze the
dump.
Data: POOLN - Pool number
BLKADR - Address of the block. Zero indicates it is the pool
descriptor itself that contains the bad pointer.

BUG.(HLT,FSPBLK,FREE,SOFT,<Block damaged>,<<T1,POOLN>,<P2,BLKADR>>,<
Cause: This is a free space problem. The header of the block does not match
its trailer.
Action: If the condition is noticed when a block is being returned to the list,
it is simply marked deassigned (and bad) but not returned to the list.
If the list header is large enough to include it, the PC, job
number and fork number of the assigner and deassigner are stored in
the header/trailer. These may give a clue as to what code caused the
damage.
If the problem persists, change the BUGCHK to a BUGHLT and analyze the
dump.

BUG.(HLT,FSPBND,FREE,SOFT,<RELFSP - Block out of range>,
<<Q1,POOLN>,<T3,CALRPC>,<P2,BLKADR>>,<
Cause: This is a free space problem. The caller to the free space
routines is trying to return a block that was not given
out by the free space manager. The block is outside the
range of free space management.
Action: Look through the dump. By looking at the stack you
should be able to determine who called for the releasing
of the block.

BUG.(HLT,FSPBPC,FREE,SOFT,<RELFSP - Bad pool count>,
<<Q1,POOLN>,<T3,CALRPC>,<P2,BLKADR>>,<
Cause: This is a free space problem. The caller to the free space
routines is trying to return a block so that when the pool count
is augmented by the blocksize, an invalid number results. The
blocksize may be in error, or the pool count may already be in
error.
Action: Look through the dump. If the blocksize is wrong, then study the
code at the calling PC for possible errors. If the pool count is
wrong, then more investigation is required. The history buffer for the
pool may contain helpful data.
Data: POOLN - Pool number
CALRPC - PC of caller to RELFSP
BLKADR - Address of block being returned
>)
BUG.(HLT,FSPDNN,FREE,SOFT,<RELFSP called OKINT>,<<T4,POOLN>,<T3,CALRPC>>,<
Cause: This is a free space problem. The calling routine is trying to release
a swapable free space block while it is OKINT. This is dangerous since
it could get interrupted and loose the block. All
free space actions should occur while NOINT.
Action: The data supplied gives the address of the calling routine. Make
the routine become NOINT when it removes the address of the block
about to be released from the database. The routine
can be made OKINT when control is returned to it.

BUG.(HLT,FSPPRE,FREE,SOFT,<RELFSP - Bad block being released>,
<<Q1,POOLN>,<T4,CALRPC>,<P2,BLKADR>>,<
Cause: This is a free space problem. The block being returned does not fit
into the free pool. The block would overlap the preceding block
in the pool.
Action: If the problem persists, change the BUGCHK to a BUGHLT. Looking at
the stack will show the caller. It is possible that the length of the
current block is incorrect. It is equally likely that the
block(s) before this block (in free space) have had incorrect
lengths on return. Thus, the caller may not be the culprit.

into the free pool. The block would overlap the succeeding block
in the pool.
Action: If the problem persists, change the BUGCHK to a BUGHLT. Looking at
the stack will show the caller. It is possible that the length of the
current block is incorrect. It is equally likely that the

Cause: The access control job has not responded with a GIVOK within the
designated time period.
Action: If this consistently happens with the same function code, you
should see if the processing of the function can be made faster.
If there is no obvious function code pattern, you may need to
increase the timeout period or rework the way in which the
access control program operates.
Data: FUNC - the GETOK function code

BUG.(HLT,GLFNF,SCHED,HARD,<GLREM - Fork not found>,,<
Cause: The scheduler is trying to remove a process from its linked list of

BUG.(CHK,HARDCE,APRSRV,HARD,<Hard cache errors--cache deselected>,,<
Cause: The hardware has detected an AR or ARX parity error that occurs
only when an address is referenced through the cache. An attempt
to reference the same address from memory with the cache turned
off has succeeded. This has happened more than the allowable
maximum number of times. The monitor will turn off the cache and
proceed.
The monitor has printed a description of the problem on the
CTY and created a SYSERR block, which will be written into
the SYSERR file.
Action: The monitor will continue to run without the cache.
However, when the front end reloads the monitor at some future
time, the front end will enable the cache. Change its configuration
file in order to avoid this until the cache is fixed.

Cause: A fork has entered a high priority scheduling condition, i.e.
PIBMP, CSKED, or JP%SYS, and has remained compute-bound for more than
5 seconds. The fork has probably malfunctioned in some way, and
the high scheduling priority is affecting overall system response.

transfer wait queue of a unit, but the arguments are illegal.
Either the arguments are null, or CONSTW is trying to remove more than
one element because it was passed more than one arguement.
>)
BUG.(HLT,ILCST1,PAGUTL,SOFT,<Illegal address in CST1 entry, cannot restart>,,<
Cause: The monitor is attempting to complete I/O that was taking place
when the system crashed. The backup address in the CST is
invalid for some core page. Note: This code is executed only
if the monitor is manually started at location EVRST. This is
not a recommended procedure.
>)
BUG.(HLT,ILDEST,PAGEM,HARD,<Illegal destination identifier to SETMPG or
SETPT>,,<
Cause: A routine has been called to change the map for a page. The
caller provided a source identifier for a page table (an SPT
index) rather than a single page. The BUGHLT indicates that
the caller provided a file page as a destination. This is
illegal when the source is a page table.
>)
BUG.(CHK,ILDRA1,SWPALC,HARD,<DASDRM - Illegal or unassigned drum address>,,<
Cause: DASDRM was called to deassign a drum address, but the drum address
provided by the caller is invalid or already unassigned.
>)
BUG.(HLT,ILDRA2,SWPALC,SOFT,<DRMIAD - Illegal drum address>,,<
Cause: AN illegal drum address was given to the DRMIAD subroutine, which
computes disk tracks and sectors.
>)
BUG.(INF,ILDSTF,DATIME,SOFT,<Illegal Daylight Saving Time flag>,<<T1,DSTFLG>>,<
Cause: Location DSTFLG contains an illegal value. The most likely case of
this bug is a new way of confusing DST that subroutine DSTCHK wasn't
informed about.
Action: None. If this BUGINF occurs, the Daylight Saving Time flag is reset
to zero. Use the default system in the monitor.
Data: DSTFLG - Daylight savings time flag
>)
BUG.(HLT,ILESCD,PAGEM,SOFT,<Monitor section pointer not shared>,
<<T1,POINTER>,<Q2,SECTION>>,<
Cause: A pointer for a monitor section has been found that is not a
share pointer. Only share pointers are expected. If other
pointer types are used, this code must be enhanced. It is possible
that the monitor section table has been clobbered.
Data: POINTER - The pointer.
SECTION - The monitor section for which it was found.
>)
BUG.(HLT,ILFPTE,PAGEM,SOFT,<ILLFPT - Illegal section number referenced>,,<
Cause: A routine was called to translate a virtual address into an
internal identifier. The BUGHLT indicates that the caller provided a
monitor address that contained an invalid section number. This
can mean any of the following:
1. The section number is larger than the maximum possible.
2. On a machine that does not support extended addressing, a
non-zero section number was provided.
>)
BUG.(HLT,ILGDA1,SWPALC,SOFT,<GDSTX - Bad address>,,<
Cause: A bad drum address was given to the GDSTX routine, which converts drum
address into indexes into the DST table. Consequently, the GDSTX
routine did not try to compute the index.
>)
BUG.(HLT,ILGDA2,SWPALC,SOFT,<GDSTX - Bad address>,,<
Cause: Bad index into the DST was computed from a drum address that was given
to GDSTX for conversion.
>)
BUG.(CHK,ILGOKM,JSYSA,SOFT,<Illegal function for GETOKM call>,<<T1,GOKFCN>>,<
Cause: The GETOKM routine was called with an unknown function code.
GETOKM handles internal GETOK requests from the monitor.
Data: GOKFCN - GETOK function code
>)
BUG.(CHK,ILIBPT,PAGUTL,HARD,<Bad pointer type in index block>,,<
Cause: SCNOFN was called to scan an index block and move all its pages to
disk but the index block contains a pointer that is not an
immediate pointer.
>)
BUG.(HLT,ILIRBL,PHYSIO,HARD,<PHYSIO - IORB link not null at ONFPWQ>,,<
Cause: The routine ONFPWQ was called to place an IORB at the front
of the position wait queue for a unit. But the link field
in the IORB pointing to the next IORB was not null.
>)
BUG.(CHK,ILJRFN,FORK,SOFT,<JFKRFH - Bad JRFN, ignored>,,<
Cause: Routine JFKRFH was erroneously called with a fork number which
is out of range. The correct range is a value less than NUFKS.
JFKRFH changes a fork number into a fork handle.
>)
BUG.(HLT,ILLDMS,APRSRV,SOFT,<BADDMS - Illegal DMS JSYS from monitor context>,
<<KIMUPC,PC>>,<
Cause: The monitor has issued a JSYS that requests a service of the
RMS-20 package. These JSYSs are legal in user mode only.
An illegal instruction trap will be given to the current
process.
Data: PC - PC in monitor address space where JSYS was invoked
>)
BUG.(HLT,ILLGO,PHYH2,HARD,<Invalid channel logout>,,<
Cause: The routine CKERR was called to check for channel errors after
an I/O operation. The operation supposedly succeeded according
to the IORB status bits. But in verifying for a
short style IORB that the I/O was done correctly, the page number
contained in the channel logout area did not match the number of the
page on which the IORB wanted to perform I/O.
>)
BUG.(CHK,ILLMJS,APRSRV,SOFT,<JSYS with E GTR 1000 executed in monitor>,
<<FPC,PC>>,<
Cause: A JSYS with E greater than 1000 has been executed in the monitor.
There should be no such cases.
Data: PC - PC of JSYS
>)
BUG.(CHK,ILLTAB,LOGNAM,HARD,<TABLK2 - Table not in proper format>,
<<Q1,TABADD>>,<
Cause: A logical name table is not in the proper alphabetic order.
Data: TABADD - Address of logical name table
>)
BUG.(HLT,ILLUUO,APRSRV,SOFT,<KIBADU - Illegal UUO from monitor context>,
<<KIMUFL,FLAGS>,<KIMUPC,PC>,<KIMUEF,EFFADR>>,<
Cause: The monitor has executed an instruction that the microcode
treats as an MUUO. The op code is not 104 (for a JSYS) or one
of the KA10 floating point instructions.
Action: Look for the software bug. Repeated occurrence of this
BUGHLT may indicate a hardware problem.
Data: FLAGS - Processor flags when MUUO was executed
PC - PC in monitor address space where MUUO was executed
EFFADR - Effective address of MUUO
>)
BUG.(HLT,ILMNRF,PAGEM,SOFT,<Illegal reference to MON ADR SPACE>,
<<T1,PFW>,<T2,FLAGS>,<T3,PC>>,<
Cause: The monitor made an illegal reference to an address in its map
and was not prepared to handle the error. The possible errors
include illegal read, write, and section number. See the page
fail word for the reason code.
This BUGHLT can also occur if an unrecoverable AR/ARX parity
error is detected on certain monitor references. In this
case, the analysis of the error will already have been
printed on the CTY.
Data: PFW - Page Fail Word
FLAGS - PC flags
PC - PC
>)
BUG.(HLT,ILOFN1,PAGEM,SOFT,<MSCANP - ILLEG IDENT>,,<
Cause: A routine has been called to scan the pages of a file to find
the first non-zero page. Its arguments include an OFN
associated with the file. The BUGHLT occurs because the caller
has passed a 0.
>)
BUG.(HLT,ILOKSK,SCHED,,<OKSKED executed when not NOSKED>,,<
Cause: A process has declared itself to be OKSKED and ready to cease running
(dismiss) until some event occurs. This BUGHLT occurs because the
process is OKSKED, indicating a mismatch of NOSKED and OKSKED states.
>)
BUG.(HLT,ILPAG1,PAGEM,SOFT,<SWPOT0 - Invalid page>,,<
Cause: A routine was called to swap out a page in core. The BUGHLT
indicates that the caller provided a bad argument, resulting
in one of the following:
1. The page is not in core.
2. The page is part of the resident monitor.
3. The page is locked in memory.
4. The page is already being swapped.
>)
BUG.(HLT,ILPAGN,PAGUTL,SOFT,<MRKMPG - Invalid page number>,,<
Cause: A routine has been called to mark a page as modified (to
set the CORMB flag in CST0). The BUGHLT indicates that the
core page number provided by the caller is invalid.
>)
BUG.(HLT,ILPDAR,PHYSIO,HARD,<PHYSIO - Illegal disk address in PAGEM request>,,<
Cause: The routine PHYSIO was called to queue up an IORB for PAGEM, but
the disk or swapping address, or unit was illegal. All such
arguments should have been checked by the caller.
>)
BUG.(CHK,ILPID1,IPCF,HARD,<CREPID - Attempt to create illegal PID>,,<
Cause: CREPID called PUTPID with an illegal PID number.
Action: If these persist, change the CHK to a HLT and examine the dump to
determine why GETPID returned an illegal PID value.
>)
BUG.(CHK,ILPID2,IPCF,HARD,<DELPID - Validated PID turned illegal>,,<
Cause: A PID which had previously been blessed by VALPID was found to be
illegal by PUTPID.
Action: If the problem continues, change this CHK to a HLT and try to
determine from a dump why the PID was OKed by VALPID and rejected
by PUTPID.
>)
BUG.(HLT,ILPLK1,PAGUTL,SOFT,<MLKPG - Illegal arguments>,,<
Cause: A routine was called to create a page in the monitor's
address space. But the caller provided a page identifier that
pointed to an existing page.
>)
BUG.(HLT,ILPPT1,PAGUTL,HARD,<UPDOFN - Bad pointer in page table>,,<
Cause: The monitor is updating the disk index block for a file.
The index block contains an address of a file page that is
incorrect for one of the following reasons:
1. It is a memory address of non-existent memory or in the
resident monitor.
2. There is no disk address for the page.
>)
BUG.(HLT,ILPPT3,PAGEM,SOFT,<Bad pointer in page table>,,<
Cause: A page fault occurred because a process touched a page whose
map entry contained access bits of 0, indicating non-existent
page. But when the monitor mapped the page table, the page's
entry was not 0. A non-existent page should always be
represented by an all-zero entry.
>)
BUG.(HLT,ILPSEC,APRSRV,SOFT,<Illegal section number>,
<<UPTPFO,PC>,<UPTPFW,PFW>>,<
Cause: While running in scheduler context, the monitor made a reference to an
address whose section number exceeded 37.
Data: PC - PC when instruction was executed
PFW - page fail word
>)
BUG.(HLT,ILPTN1,PAGEM,SOFT,<MRPACS - Illegal PTN>,,<
Cause: A routine has been called to determine the possible access to a
page. Its arguments include the SPT index for the page table
associated with the page. The BUGHLT occurs because the caller has
passed a 0.
>)
BUG.(HLT,ILRBLT,PHYSIO,HARD,<PHYSIO - IORB link not null at ONF/STWQ>,,<
Cause: One of the routines ONFTWQ or ONSTWQ was called to insert an IORB
into the transfer wait queue, but the link word for that IORB
was not zero. IORBs should always contain a null link when
they are created or removed from a queue, so that many queue
handling errors can be detected.
>)
BUG.(HLT,ILSPTH,PAGEM,SOFt,<SETPT - SPTH inconsistent with XB>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file page for which
the index block has a share pointer. The share pointer points
to an SPT slot. The BUGHLT indicates that the SPT slot is not
owned by the file page whose map word points to it. This
indicates an inconsistency in the monitor's data.
>)
BUG.(HLT,ILSPTI,PAGEM,SOFT,<Illegal SPT index given to SETMXB>,,<
Cause: A routine has been called to change the map for a page. The
caller provided a source identifier for a page table (an SPT
index) rather than a single page. The BUGHLT indicates that
the source identifier is an invalid SPT index, larger than the
maximum value allowed.
>)
BUG.(HLT,ILSRC,PAGEM,SOFT,<Illegal source identifier given to SETPT>,,<
Cause: A routine has been called to change the map for a page. The
caller is expected to provide an identifier for the source
that is of the form (SPT index,,page number). The BUGHLT
indicates that the right half of the identifier contains an illegal
value (that exceeds 777).
>)
BUG.(HLT,ILSWPA,PAGEM,SOFT,<SWPIN - Illegal swap address>,,<
Cause: A routine has been called to swap a page into core. The backup
address for the page is of an illegal format.
>)
BUG.(HLT,ILTWQ,PHYSIO,HARD,<PHYINT - TWQ OR PWQ INCORRECT>,,<
Cause: In the PHYINT routine to handle an interrupt, after the lower
level interrupt code has returned, a check is made to see if
the IORB returned matched the first element of either the position
wait queue or the transfer wait queue. The returned IORB did not match
the first element in the queue checked.
>)
BUG.(HLT,ILTWQP,PHYSIO,HARD,<PHYSIO - PWQ or TWQ tail pointer incorrect>,,<
Cause: The pointer to the last element in the position wait queue or
transfer wait queue (UDBPWQ or UDBTWQ) points to an IORB which
has a non-null link to further IORBs. This is checked in various
routines such as ONTWQ, ONPWQ, ONSTWQ, ONFPWQ, CONSTW, or CONSPW.
>)
BUG.(HLT,ILULK1,PAGUTL,SOFT,<MULKPG - Tried to unlock page not locked>,,<
Cause: A routine was called to unlock a core page, but the page was
not in core, indicating it could not have been locked.
>)
BUG.(HLT,ILULK2,PAGUTL,SOFT,<Tried to unlock page not locked>,,<
Cause: A routine was called to unlock a core page, but the page's
lock count was 0.
>)
BUG.(HLT,ILULK3,PAGUTL,SOFT,<MULKMP - Illegal monitor address>,,<
Cause: A routine was called to unlock a core page in the monitor's
address space but the caller provided a page identifier that did not
point to the monitor's map.
>)
BUG.(HLT,ILULK4,PAGUTL,SOFT,<MULKCR - Illegal core page number>,,<
Cause: A routine was called to unlock a core page. The caller provided
a page number that was illegal because of one of the following:
1. The page is never locked because it is part of the resident
monitor
2. The page does not exist in physical memory.
>)
BUG.(HLT,ILUST1,PHYSIO,HARD,<PHYSIO - Unit status inconsistent at SIO>,,<
Cause: The STRTIO routine was called to start IO on a unit for an IORB,
but the unit or controller status indicated that the unit was
already active. IO should never be started on an active drive.
>)
BUG.(CHK,ILUST2,PHYSIO,HARD,<PHYSIO - Unit status inconsistent at SPS>,,<
Cause: The routine STRTPS was called to begin a positioning request
for a unit, but the status indicated that the unit was already
active and the transfer wait queue was nonempty.
>)
BUG.(HLT,ILUST3,PHYSIO,HARD,<PHYSIO - SCHSEK - Impossible unit status>,,<
Cause: The SCHSEK routine was called to start a position request for
a unit, but the status of the unit indicated it was not idle.
SCHSEK should only be called when a unit becomes inactive.
>)
BUG.(HLT,ILUST4,PHYSIO,HARD,<PHYSIO - Controller active at SPS>,,<
Cause: The routine STRTPS was called to begin positioning on a
unit, but the controller status indicated it was already
busy.
>)
BUG.(HLT,ILUST5,PHYSIO,SOFT,<PHYSIO - Illegal channel or controller state
at STKIO>,,<
Cause: The STKIO routine was called to stack up a second command for a
channel, so that the CDB and KDB (if it exists) should have been
marked as active. However, at least one of them wasn't active.
>)
BUG.(HLT,ILUST6,PHYSIO,SOFT,<PHYSIO - Illegal unit state at STKIO>,,<
Cause: The STKIO routine was called to stack up a second command for
a channel, but the unit either was not active or was doing
positioning.
>)
BUG.(HLT,ILXBP,PAGEM,SOFT,<SETPT - Bad pointer in XB>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file page. The BUGHLT
indicates that the index block for the file contains an indirect
pointer in memory. Only share pointers and immediate pointers
are legal for index blocks.
>)
BUG.(INF,IMINX1,IMPANX,HARD,<Unusual ANI interrupt, CONI ANI is>,<<T1,D>>,<
Cause: The monitor received an interrupt from the input side of the AN20
when it was supposed to be idle. This may indicate a hardware
problem with the AN20.
>)
BUG.(HLT,IMPBAD,IMPDV,SOFT,<IMPDV: Attempt to return a buffer not in range>,,<
Cause: The internet 1822 buffer facility has been called to return a buffer
which is not an 1822 buffer.
>)
BUG.(INF,IMPERN,IMPDV,HARD,<IMPDV: Received error notification message>,
<<T1,HOST>,<T2,LINK>,<T3,TYPE>,<T4,SUBTYP>>,<
Cause: The IMP has detected an error in the last message transmitted to it.
The error is after the leader but before the end of the message. This
may indicate possible hardware problems in the AN20.
>)
BUG.(INF,IMPHNW,IMPDV,SOFT,<IMPDV: LHOSTN disagrees with the IMP>,,<
Cause: The monitor has received a NOP message from the IMP with an address
that disagrees with our known address. The IMP has been known to send
corrupted NOP message in the past but the problem is probably
that the SYSTEM:INTERNET.ADDRESS file has the wrong address for the
AN20 interface.
>)
BUG.(HLT,IMPIBF,IMPANX,SOFT,<Internet buffers fouled>,<<CX,D>>,<
Cause: The monitor was trying to obtain an internet buffer and none were
available. This is a problem because the available buffer count
was non-zero.
>)
BUG.(INF,IMPINC,IMPDV,SOFT,<IMPDV: Received incomplete transmission message>,
<<T1,HOST>,<T2,LINK>,<T3,TYPE>,<T4,SUBTYP>>,<
Cause: The IMP has declared that the last message transmitted to it
was incomplete. This may indicate possible hardware problems
with the AN20 or the following conditions (subtypes):
0. The destination host did not respond quickly enough to the message.
1. The message was too long.
2. The AN20 took more than 15 seconds to transmit the message to the
IMP.
3. The message was lost in the network due to an IMP or circuit failure.
4. The IMP could not accept the message within 15 seconds due to a
unavailable resources.
5. The IMP had an IO failure during the receipt of this message.
>)
BUG.(HLT,IMPIWW,IMPDV,SOFT,<IMPDV: Internet bfr word size wrong>,,<
Cause: The monitor has detected an illegal size in the NBBSZ field of an
internet buffer. This indicates the buffer is probably smashed.
This is probably a software problem.
>)
BUG.(HLT,IMPLKF,IMPDV,SOFT,<IMPDV: Attempt to lock buffer on freelist>,,<
Cause: The monitor has attempted to lock a buffer into memory in preparation
for IO and has determined that the buffer is not assigned or has been
smashed. This probably indicates a software problem.
>)
BUG.(CHK,IMPRMI,IMPDV,SOFT,<IMPDV: Regular message on irreg queue>,,<
Cause: The monitor has detected a type zero message on the irregular message
queue. This is not supposed to happen and indicates a software problem
in the monitor.
>)
BUG.(HLT,IMPULF,IMPDV,SOFT,<IMPDV: attempt to unlock buffer on freelist>,,<
Cause: The monitor has either attempted to unlock a buffer on the free
buffer list or the buffer is smashed. This probably indicates a
software problem.
>)
BUG.(HLT,IMPUUO,APRSRV,HARD,<Impossible MUUO>,,<
Cause: The monitor was called at its MUUO handler because the user
executed an MUUO. However, the op code reported by the
microcode is in the range 1-37, which should have caused
an LUUO.
>)
BUG.(HLT,IMPVBD,IPFREE,SOFT,<IMPDV: Attempt to return a buffer with the
address smashed>,,<
Cause: The internet 1822 buffer facility has been called to return a buffer
which has a bad address.
>)
BUG.(INF,IMPXBO,IMPDV,SOFT,<IMPDV: Irreg msg buffer overflow>,,<
Cause: The irregular message buffer has overflowed and the monitor has had
to discard an irregular message (message type non zero) from the IMP.
This tends to indicate a possible hardware with the AN20 or a problem
with the IMP. Analysis of other BUGxxx information should shed light
on the real problem.
>)
BUG.(INF,IMPXUT,IMPDV,SOFT,<IMPDV: Received irreg msg with unknown link or
type>,<<T1,HOST>,<T2,LINK>,<T3,TYPE>,<T4,SUBTYP>>,<
Cause: The monitor received an irregular message that either could not be
identified or is not supported by the monitor.
>)
BUG.(INF,INDCNT,DTESRV,HARD,<DTESRV - Bad indirect count>,<<A,DTENO>>,<
Cause: The DTE was attempting to complete an indirect but the count in
the data being sent does not match the count in the indirect
packet.
Data: DTENO - DTE number.
>)
BUG.(HLT,INGGP0,IPIPIP,SOFT,<GWYINI: Crucial storage missing>,,<
Cause: During TCP/IP initialization the monitor was unable to obtain the
free space needed for gateway message processing. This probably
indicates that internet free space is corrupted.
>)
BUG.(HLT,INGWA1,IPIPIP,SOFT,<INQINI: Free Storage gone>,,<
Cause: During system initialization no internet free space was available
for the initialization of the internet special queues.
>)
BUG.(HLT,INTBUF,IPIPIP,SOFT,<IPIPIP: Packet size smashed when unlocking

Cause: The internet buffer locking facility was called to unlock
a buffer which appears to have a smashed local header.
>)
BUG.(HLT,INTDHF,IPIPIP,SOFT,<INTDWN -- Impossible failure of NETHSH>,,<
Cause: The internet network hashing routine has failed to find the local
network. This probably indicates that the network hash table is
corrupted.

BUG.(HLT,INTNQ2,IPIPIP,SOFT,<DeQ: Item not queued>,,<
Cause: The TCP/IP list dequeuing facility was called for an item
which was not queued on a list.
>)
BUG.(HLT,INTWA0,IPIPIP,SOFT,<RELBFR: Bit table fouled>,,<
Cause: The TCP/IP release wait bit mechanism was called to release a
wait bit and the wait bit facility was determined to be corrupted.
>)
BUG.(CHK,INTWA1,IPIPIP,SOFT,<SETWTB: Wait bit not assigned>,,<
Cause: The TCP/IP wait bit facility was called to set a wait bit and
the wait bit has not been assigned.

BUG.(HLT,INVDTE,DTESRV,SOFT,<DTEQ - Invalid DTE specified>,,<
Cause: The DTE request queuer for outgoing messages has been given
an invalid (greater than 3) DTE number.
Action: Look at the dump. The stack should indicate the calling
routine.
>)
BUG.(HLT,IOPGF,APRSRV,SOFT,<IO page fail>,<<Q1,IOP>>,<
Cause: An APR interrupt occurred because an interrupt instruction caused
a page failure. This probably indicates that the interrupt instruction
provided by the monitor referenced a page that was not in memory.
The monitor has already checked for a DTE that made the reference
and found none. (However, it is possible for a software bug
to cause a DTE to generate an I/O page fail that the monitor
cannot detect.) The monitor has printed a description of the problem
on the CTY.
Data: IOP - IOP word
>)
BUG.(CHK,IPABFL,IPNIDV,SOFT,<ARP input buffer list fouled>,,<
Cause: The internet ethernet software has detected that the buffer list for
the ARP protocol is smashed. This probably indicates a software
problem.

BUG.(CHK,IPACFA,IPCIDV,SOFT,<SCA ACCEPT failed>,,<
Cause: The internet SCA interface attempted to accept a connection and
failed.
>)
BUG.(CHK,IPARPE,IPNIDV,SOFT,<ARP did not initialize>,<<T1,ERROR>>,<
Cause: The ethernet ARP (Address resolution protocol) portal did not initialize.
This is probably a temporary resource allocation problem.

BUG.(CHK,IPDWNS,IPNIDV,SOFT,<Datagram was not sent>,<<T1,ERROR>,<SRV,SERVICE>>,<
Cause: The internet ethernet software passed a buffer to NISRV to be sent and
and an error was returned. This usually indicates that the KLNI has
changed state and IPNIDV has not yet been notified. This should be
a temporary condition.
>)
BUG.(INF,IPETHA,IPNIDV,SOFT,<Ethernet address change, IPNI shutting down>,,<
Cause: The internet ethernet software has received an address changed
callback from NISRV and the ARP protocol is disabled. The ARP
protocol is needed to handle this situation. Internet ethernet
service has been terminated.

BUG.(INF,IPTENC,IPNIDV,SOFT,<Received a trailer encapsulated packet>,
<<T1,ETH1>,<T2,ETH2>,<T3,PROTO>>,<
Cause: The monitor has received a trailer encapsulation IP datagram
over the Ethernet.
Description:
A system on the Ethernet is using trailer encapsulation
formats for the transmission of IP datagrams. TOPS-20 (and
most other operating systems) does not support trailer
encapsulation. Some Berkeley Unix and VMS TCP/IP
implementations support trailer encapsulation in an effort to
enhance their Internet performance characteristics.
Action: Stop the indicated systems from using trailer encapsulation.
Additional Data:
Ethernet address of host sending trailer encapsulation in octal and
the protocol type received.

Cause: An unexpected error has occurred in Job 0 which results
in control being transferred to the default error handler.
This has happened during job 0 initialization.
The error handler will attempt to reset the context and
continue at the specified error address,
however some system resources may be
hung as a result of locks not being cleared. The stack
can be examined to determine what was in progress when
the error occurred.

BUG.(HLT,JSBNIC,PAGUTL,SOFT,<SETPPG - JSB not in core>,,<
Cause: The monitor is establishing the context for running a
process by making its per-job area part of the
monitor's map. It is about to copy the SPT entry for the
JSB into a special SPT slot. But the JSB is not in core.
>)
BUG.(HLT,JSTERR,FREE,SOFT,<JSB stack error>,,<
Cause: This is a problem with the JSB-stack logic; the count for the stack
indicated that free cells were available, however none could be
found.
Action: Analyze the dump.
>)
BUG.(HLT,JTENQE,SCHED,SOFT,<JTENQ with bad NSKED>,,<
Cause: A process has attempted to lock the JSYS trap lock and found
it already locked. The process will enter a queue and dismiss until
the lock becomes available. The BUGHLT occurs because when the process
decrements its NOSKED counter, the value does not go to 0. This
means that the process is still NOSKED or it was OKSKED when it
should have been NOSKED.
>)
BUG.(CHK,KCPFH1,PAGEM,HARD,<Unexpected page fault code (illegal age)>,,<
Cause: A page fault occurred in which the code indicated that a CST entry had
an illegal age when the corresponding virtual address existed in the
hardware's translation buffer. We expect to clear the pager when we
set an illegal age, so this condition should never occur.
Action: No action is required. The monitor proceeds as if the translation did
not exist.
>)
BUG.(HLT,KCPFH3,PAGEM,SOFT,<Illegal pointer>,,<
Cause: A page fault occurred indicating that the microcode found an illegal
pointer. Its type field contained 4, 5, 6, or 7.
Action: Debug the code that created the pointer.
>)
BUG.(CHK,KCPFH5,PAGEM,SOFT,<Illegal PXCT>,,<
Cause: A page fault occurred indicating that a PXCT was executed with the
current AC block and the previous AC block set to the same value.
Action: The monitor is not coded to run under these conditions. Most likely,
some new flags word contains 0 in the PAB and CAB fields. Find the
code that did this, and correct it.
>)
BUG.(HLT,KCPFH7,PAGEM,SOFT,<Illegal interrput vector>,,<
Cause: A page fault occurred indicating that the microcode found a all-zero
interrupt vector word when attempting to give an interrupt. This
should cause an I/O page fail and not a normal page fault.
Action: Find the reason for the zero interrupt vector word (probably a software
bug). Also find out why the microcode gave a normal page fault for
this condition.

Cause: This message is from TAPE. TAPE sends IPCF messages to MOUNTR under
certain conditions, such as volume switch. TAPE was unable to send
the IPCF message. The user program involved will get an error
return to its tape operation.
Action: There are many reasons IPCF refuses to send a message. The IPCF error
code is passed back to the user. If it is a resource problem, try
to improve system resources. If it seems like a monitor bug, change
the BUGINF to a BUGHLT and find out what the monitor is doing wrong

BUG.(HLT,NSKDIS,SCHED,HARD,<Dismiss while nosked or with non-res test
address>,,<
Cause: A process has declared its intention to cease running (dismiss) until
a particular event occurs. The scheduler will test for the occurrence
of the event by calling a routine that the process has provided. The
BUGHLT occurs if one of the following happens:
1. The process has already declared itself to be
NOSKED, thereby preventing the running of other processes;
2. The test routine is in part of the monitor's swappable code
and could therefore cause an illegal page fault in the
scheduler.
>)
BUG.(CHK,NSKDT2,PAGEM,SOFT,<PGRTRP - Bad NSKED or INTDF>,,<
Cause: When a page fault occurred, the running process's interrupt
indicator had an abnormally low value. This could
cause interruptions when it should not. The monitor
has set the value to prevent interruptions, but this indicates
a bug in which too many OKINT's have been executed.

LD.MAX defines the number of controllers known by D36PAR, and
thus by NTMAN. The most likely cause of this bug is a trashed
AC.
Note:
A controller is any device driver to which a router will interface.
It is currently used to define the name of a Circuit/Line,
under the assumption that each Kontroller will control only
a single line type.

BUG.(CHK,NTMLTR,NTMAN,SOFT,<Line type is out of range>,,<
Cause: To determine entries to return (for function .NTSHO),
it is necessary to know the Line type (CI,NI,DTE,...).
Other entities (Nodes,Modules) should have this field
zero. This field is set by ENTCVT.

>,NTEUFO)
BUG.(CHK,NTMSQF,NTMAN,SOFT,<Signal queue full>,,<
Cause: The signal queue was full when a new signal was logged.
This might be caused by a malfunctioning NMLT20 that does not
read the signals from the signal queue, or it may be caused by
a DECnet device driver going bad. A signal is used to tell
NMLT20 that a device needs attention/reload.
Action: Restart NMLT20, or turn off malfunctioning DECnet device.
If necessary, reload any devices by hand
>,EVSIG2)
BUG.(CHK,NTNBFS,D36COM,SOFT,<No buffer supplied>,,<
Cause: The routine NTPARM was called to handle a network management parameter.
The caller of NTPARM said that it expects the call from NTMAN to
supply a buffer for the parameters to be read from or stored into.
None was supplied.

BUG.(CHK,NVTILS,TTPHDV,SOFT,<NRT link in unexpected state>,,<
Cause: NRT's host service has been called by DECnet for a link in
an unexpected state.
Action: Determine whether the link indeed is in an unexpected state, or
whether it is in a state which NRT must deal. If the former,
the problem is probably in DECnet, if the latter, code must
be added to NRT.

BUG.(CHK,NVTINP,TTPHDV,SOFT,<NRT Input to DECnet failed>,,<
Cause: An input call to DECnet's SCTNSF entry point failed unexpectedly.
Action: Examine the DECnet error code in register T1.
>)
BUG.(CHK,NVTNHB,TTPHDV,SOFT,<NRTHBR should never be called>,,<
Cause: DECnet has called NRT's host service at its "hiber" address.
This should never happen, since NRT always uses asynchronous
calls to DECnet.
Action: Find a DECnet call which has the .NSWAIt flag on and turn it
off, being sure that the surrounding code can handle asynch
I/O. If none is found, DECnet must be in error.
>)
BUG.(CHK,NVTOUT,TTPHDV,SOFT,<NRT output to DECnet failed>,,<
Cause: An output call to DECnet's SCTNSF entry point failed unexpectedly.
Action: Examine the DECnet error code in register T1.
>)
BUG.(CHK,NVTPCL,TTPHDV,SOFT,<Partial Configuration Msg Loss>,,<
Cause: NRT's host service failed to send the configuration message in
a single DECnet message segment.
Action: If the message segment size for the link is really less than
ten bytes, it should probably be enlarged, else the code will
have to deal with the possibility of segmented configuration
messages.
>)
BUG.(HLT,NVTSAB,TTPHDV,SOFT,<No memory for NRT's SAB>,,<
Cause: NRT's initialization code was unable to get resident free

BUG.(CHK,NVTWWC,TTPHDV,SOFT,<Wrong Channel on Connect Wait Wake>,,<
Cause: NRT's host service has been waked for a circuit which is not
the logical link in connect wait state and which has no TTY
line number associated with it.
Action: Either the connect wait link is out of phase and should be corrected
or an active link has lost its TTY line number which should be
in the DECnet PSI mask.
>)
BUG.(CHK,NVTWWN,TTPHDV,SOFT,<No NRTCWN Connect Wait Wake>,,<
Cause: NRT's host service has been waked for a circuit which has no TTY
line number associated with it, yet there is no NRB for a
logical link in connect wait state.
Action: Either the NRB pointer in NRTCWN has been stepped on or an active
logical link has lost its TTY line number which should be in the
DECnet PSI mask.
>)
BUG.(CHK,NWJTBE,FORK,SOFT,<No free JTB blocks>,,<
Cause: Word JTBFRE in the JSB has bit n on if JSYS trap block n is
available. The NEWJTB routine assigns trap blocks, looking in JTBFRE
for a bit on. If no bit is found to be on in JTBFRE, the NWJTBE bugchk
occurs.

BUG.(HLT,OFFONX,JSYSF,SOFT,<ARRST - File marked offline has index blk ptr>,,<
Cause: In restoring an offline file, it was discovered the file already
has some contents.
>)
BUG.(HLT,OFFSPE,PAGUTL,SOFT,<OFFSPQ - Page not on SPMQ>,,<
Cause: A routine has been called to remove a core page from the special
memory queue. If a page is on the queue, its age should be
PSSPQ. The BUGHLT indicates that the age is incorrect. The
entry may or may not actually be on the queue. The caller is
expected to ensure that the page is on the queue.

BUG.(HLT,OFJFBD,DISC,SOFT,<OFNJFN - OFNJFN found bad data>,,<
Cause: An OFN was found whose bits indicated that it was or was not a
secondary index block. SPTO4 was found to disagree.
>)
BUG.(HLT,OFNBDB,PAGUTL,SOFT,<OFN bad data base>,,<
Cause: There are multiple causes of this BUGHLT. They all indicate some
error in the monitors internal OFN data. The cause of the BUGHLT
can be found by examining the dump.
>)
BUG.(HLT,OKSKBG,SCHED,SOFT,<OKSKD0 - OKSKED when not NOSKED>,<<CX,ADR>>,<
Cause: An OKSKED or OKSKD1 was done when the code was not NOSKED.
This is bad as sensitive code may be getting ruined because
of races etc.. A NSKDIS would probably have resulted when a
DISMS was done later on.
Data: ADR - Address of caller
>)
BUG.(HLT,OPOPAC,SCHED,HARD,<MRETN - Tried to over-pop AC stack>,,<
Cause: When a JSYS is executed from within the monitor, the
AC's of the current process are stored in a special area in the
monitor. This area consists of several 20-word blocks that are used
successively as one JSYS calls another.
As each nested JSYS returns, the monitor's pointer to this area of
memory is decremented. The BUGHLT indicates that the pointer has
been decremented too far. This indicates either a clobbered pointer,
or an attempt to return from a JSYS without having entered one.
>)
BUG.(HLT,OVFLOW,PAGUTL,SOFT,<ASOFN - Allocation table overflow>,,<
Cause: The monitor maintains information for disk quota enforcement
in two parallel tables called the allocation tables. These
contain one entry for each directory to which at least one OFN
is assigned (that has at least one file open). The size
of these tables is the maximum number of OFN's; therefore even
if every OFN were associated with a unique directory, there
should be enough room in the allocation tables. The BUGHLT
indicates that the tables have overflowed.
>)
BUG.(INF,OVRDTA,PHYSIO,HARD,<PHYSIO - Overdue transfer aborted>,
<<T1,CHAN>,<T2,CONTRL>,<T3,UNIT>,<T4,FUNC>>,<
Cause: The routine UNICKT checks the status of each unit periodically. During
one such check, some unit had an active IORB which timed out. The I/O
operation had been started, but not completed within 17 seconds. This
BUGINF can be followed by other BUGINFs or BUGCHKs when the device
finally responds (such as PH2DNA).
Action: If the involved device is a tape drive controlled by a DX20, a
common cause of the BUGINF is the microcode halting. Reloading
the microcode will fix the problem. Other causes are hardware
failures, and Field Service should examine the problem.
Data: CHAN - The channel number

>)
BUG.(HLT,PAGLCK,PAGUTL,SOFT,<DESPT - Page locked>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. The caller is expected to ensure that
the SPT is no longer in use. The BUGHLT indicates that the
SPT slot is associated with a page that has been locked into
memory even though the SPT share count is 0. This indicates
an inconsistency in the monitor's data base. Probably the page
was used as a page table, and not all its page pointers were
cleared properly. A page table is locked in memory once for
each page in memory to which it points.
>)
BUG.(HLT,PAGNIC,PAGUTL,SOFT,<GETCPP - Page not in core>,,<
Cause: A routine was called to convert a virtual address or page id
to its corresponding core page. But the page table is not in
core.

BUG.(HLT,PGNDEL,PAGEM,SOFT,<REMFPB - Page not completely deleted>,,<
Cause: A page has been marked as partially deleted and placed on a
queue. The routine that processes the queue has found that the
page still has a backup on disk. The routine that marked the
page should have deleted all backup pages.
>)
BUG.(HLT,PGRIXM,PAGUTL,SOFT,<PGRINI - Boot overlaps resident tables>,,<
Cause: The values in BUTPHY indicate that BOOT has been left in pages
which are expected to be available for resident code or

Cause: The routine RH2INT was called to handle an interrupt on the
RH20 and the CONI said done was up, but no I/O transfer was
in progress. If an OVRDTA had previously occured, and the
device finally responds, this BUGINF can happen. This usually
indicates a hardware failure.
Action: Call Field Service.
Data: CHAN - The channel number

Cause: The routine RH2CHK was called for a periodic check on the status
of the RH20, and it discovered that the channel assignment of
the RH20 changed from what it should be. This usually indicates
a hardware malfunction. This situation is serious as it could
cause file structure damage.

BUG.(HLT,PH2WUI,PHYH2,HARD,<Wrong unit interrupted>,,<
Cause: The routine RH2INT was called to handle an interrupt, and it
determined that I/O had finished for a unit. The operation was a write
operation. The CONI said that a particular unit completed the I/O, but
that was not the unit to which the I/O was begun. This BUGHLT occurs on
the second such error for a particular IORB.

BUG.(INF,PHYICE,PHYSIO,HARD,<PHYINI - Failed to assign resident STG>,,<
Cause: The routine PHYALC was called to allocate storage for data such
as a CDB, KDB, or UDB, but there was not enough free resident

any device for which it cannot build tables.
>)
BUG.(HLT,PHYLTF,PHYSIO,HARD,<PHYSIO - SCHLTM - Unexpected LATOPT failure>,,<
Cause: The routine SCHLTM was called to do disk latency optimization,
by scanning all units for the best IORB. A unit was found to have a
nonnull transfer wait queue, but the lower level code to select the
best IORB for that unit gave the non-skip return, indicating that no
IORBs existed.

BUG.(HLT,PI0ERR,APRSRV,HARD,<Unvectored interrupt on channel 0>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI
channel 0. This is not supposed to happen. This could possibly
be faulty hardware generating incorrect PI requests.
>)
BUG.(CHK,PI1ERR,APRSRV,HARD,<Unexpected unvectored interrupt on channel 1>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI

generating spurious PI requests.
>)
BUG.(CHK,PI2ERR,APRSRV,HARD,<Unexpected unvectored interrupt on channel 2>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI

channel. This could possibly indicate faulty hardware that is
generating spurious PI requests.
>)
BUG.(CHK,PI5ERR,STG,HARD,<Unexpected unvectored interrupt on channel 5>,,<
Cause: If no devices are supposed to exist on the system which cause
unvectored interrupts on channel 5, and more than ten such interrupts
happen, this bugchk will occur. This bugchk is only possible if
your system has no dectape and no card punch and no papertape
reader. It has been observed that the DX20 occasionally causes
random interrupts. Having the bugchk not happen until ten such
interrupts have been received tends to prevent the bugchk from
happening.
>)
BUG.(CHK,PIDFLF,IPCF,HARD,<CREPID - Free PID list fouled up>,,<
Cause: An invalid PID number was passed to GETPID by CREPID. This value
passed was retrieved from PIDLST.
Action: If these BUGCHKs persist, look at the PIDLST and try to determine
how it was corrupted.
>)
BUG.(CHK,PIDOD1,IPCF,HARD,<MUTCHO - PID count overly decremented>,,<
Cause: When attempting to tranfer ownership of a PID from one job to

BUG.(HLT,PIITRP,SCHED,HARD,<Instruction trap while PI in progress or in
scheduler>,<<LSTERR,LSTERR>,<LSTIPC,ERRPC>>,<
Cause: An error occurred, resulting in an illegal instruction trap. If a JSYS
was being executed by the monitor, the process would receive an
error return. However, in this case the error occurred while a
hardware interrupt (PI) was being processed, or while the monitor was
executing code that starts the scheduler cycle.
Data: LSTERR - Last error code. This may indicate where error was
generated.
ERRPC - PC at which error was generated.
>)
BUG.(HLT,PINIC1,APRSRV,SOFT,<MAPIPG - Page table not in core>,,<
Cause: A routine has been called to map a page into a special
address slot. The requested page is not in memory.
>)
BUG.(HLT,PIRACE,APRSRV,SOFT,<MAPIPG - Called with PI on>,,<
Cause: This routine uses a MMAP entry which may be used at PI level.
To avoid races the PI should be off when it is called.
This particular caller did not turn off the PI.
Action: Check the stack to find the caller.
>)
BUG.(HLT,PISKED,SCHED,HARD,<Entered scheduler with PI in progress>,,<
Cause: The monitor started to execute the main scheduler routine. The
hardware indicates that a hardware interrupt is being held. Since
hardware interrupts operate at a higher priority than the scheduler,
this should not happen.
>)
BUG.(HLT,PITRAP,PAGEM,SOFT,<Pager trap while PI in progress>,,<
Cause: A page fault occurred while a hardware interrupt was in progress.
This can be the result of hardware failure or a software bug. If
the page fail word indicates an AR or ARX parity error, the monitor
has printed an analysis of the problem on the CTY, and a SYSERR
entry will be created when the monitor is rebooted.
>)
BUG.(HLT,PLKMOD,PAGEM,SOFT,<Page lock overly decremented>,,<
Cause: The monitor decremented the lock count of a page past zero.
This indicates a software problem.

BUG.(CHK,PM2SIO,PHYM2,HARD,<PHYM2 - Illegal function at start IO>,,<
Cause: The IORB function code provided to TM2SIO is less than or equal to
zero or the short form (PAGEM) request bit is set in the IORB.
>)
BUG.(CHK,PM8SIO,PHYM78,HARD,<PHYM78 - Illegal function at start IO>,,<
Cause: This bugchk can be caused by trying to write an odd number of
words to a TU78 that is set for the high density mode. If
T2 is odd, this is probably the cause.
>)
BUG.(HLT,PPGOFN,PAGEM,SOFT,<SPHYPT - Destination is OFN>,<<T4,OFN>>,<
Cause: SPHYPG or SPHYPG has been given an destination argument which
is an OFN. This type of mapping may only be done into
non-file page tables.
Data: OFN - The OFN.
>)
BUG.(HLT,PRONX2,APRSRV,HARD,<NXM detected by processor>,,<
Cause: A page fault occurred indicating that the processor
attempted to access a memory that did not respond within
a preset time. The monitor is presently running in
process context. The interrupt system is on. Since
non-existent memory also produces an APR interrupt,
which results in an APRNX1 BUGHLT,
this BUGHLT does not normally occur.
Action: See APRNX1. Note, however, that the occurrence of this BUGHLT
instead of APRNX1 may indicate a failure in the interrupt
system.
>)
BUG.(HLT,PSBNIC,PAGUTL,SOFT,<SETPPG - PSB not in core>,,<
Cause: The monitor is establishing the context for running a
process by making its per-process area part of the
monitor's map. It is about to copy the SPT entry for the
PSB into a special SPT slot but the PSB is not in core.
>)
BUG.(CHK,PSINSK,SCHED,HARD,<PSI From NOSKED or CRSKED context>,,<
Cause: This process is NOSKED or CSKED, but is not NOINT.
>)
BUG.(HLT,PSISTK,SCHED,HARD,<PSI Storage stack overflow>,,<
Cause: A software interrupt occurred while a process was running
in the monitor. The monitor is saving information regarding
the state of the process so that in can restore that state
when the process dismisses the interrupt. The BUGHLT indicates
that the storage area has overflowed.
>)
BUG.(HLT,PTAIC,PAGEM,SOFT,<SWPIN - PT page already in core>,,<
Cause: A routine has been called to swap a page into core. The id for
the page indicates that it is a data page. The BUGHLT
occurred because the entry in its page table contains a core
address.
>)
BUG.(HLT,PTDEL,PAGUTL,SOFT,<DESPT - PT not deleted>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. It assumes that the slot was used as a
page table. The BUGHLT occurs because the SPT entry or its
backup address is on disk. The caller probably has used the
wrong routine in releasing an OFN.
>)
BUG.(HLT,PTMPE,APRSRV,HARD,<Page table parity error>,,<
Cause: The monitor encountered multiple page table parity errors.
>)
BUG.(HLT,PTNIC1,APRSRV,SOFT,<SWPIN - Page table not in core>,,<
Cause: A routine has been called to map a page table into a special
page used only by the swapping routines. The caller is expected
to provide an identifier for a page that is in memory. When a
page is in memory, the page table that points to it must be
in memory. The BUGHLT indicates that the storage address for
the page table is not a valid core page. This can indicate that the
page is not in memory or that its memory address is larger
than the physical memory on the machine. The most likely
cause is corruption of the monitor's data base.

BUG.(HLT,PTNON0,PAGEM,SOFT,<SETPT0 - Previous contents NON-0>,,<
Cause: A routine has been called to change the map for a page of a
process. The caller is expected to have unmapped any previous
contents of the page. The BUGHLT indicates that the page table
contains a non-zero pointer for the page.
>)
BUG.(HLT,PTOVRN,PAGUTL,SOFT,<UPDPGS - Count too large>,,<
Cause: A routine has been called to update pages of a file on the disk
to which a specified index block (OFN) points. The caller
provides a starting page and a count. The BUGHLT occurs
because the sum of the two extends beyond the end of the
index block.

BUG.(CHK,PTPTE1,APRSRV,HARD,<Page table parity error>,<<UPTPFW,PFW>>,<
Cause: A page table entry has bad parity. The monitor will clear
the entry and try again. If it fails repeatedly, PTMPE
will result.
Data: PFW - Page fail word
>)
BUG.(HLT,PVTRP,APRSRV,HARD,<Proprietary violation trap>,,<
Cause: A page fault occurred indicating a proprietary violation while
the monitor was running in scheduler context. An instruction in
a public page attempted to reference a concealed page. Since TOPS-20
uses only concealed mode, this BUGHLT should never happen.
>)
BUG.(HLT,PWRFL,APRSRV,HARD,<Fatal power failure>,,<
Cause: The monitor has been started at the power-fail recovery
code and is attempting to recover. However, the loss
of power that preceded this occurred too quickly to
allow an orderly shutdown. Therefore the monitor will
be reloaded. This BUGHLT will be preceeded by the messages:
"Attempting automatic restart..."
"PWRDWN .NE. -1, restarting..."
>)
BUG.(CHK,PWRRES,APRSRV,HARD,<Power restart>,,<
Cause: The monitor was started at the power fail recovery code
and is attempting to recover. This BUGCHK will be preceded by:
"Attempting automatic restart..."
"Attempting to continue system"
This indicates that an an orderly shutdown was
accomplished before the power fail so the system will
continue.

there is a consistency check performed. The block is merged into
existing blocks that follow it in free space. This block overlaps
into existing free blocks. It cannot be merged.
Action: If the problem persists, change the BUGCHK to a BUGHLT. Looking at
the stack will show the caller. It is possible that the length of the

BUG.(CHK,RELINT,FREE,SOFT,<RELFRE called OKINT>,<<A,CALLER>>,<
Cause: This is a free space problem. The calling routine is trying to release
a swapable free space block while it is OKINT. This is dangerous since
it could get interrupted and loose the block. All
free space actions should occur while NOINT.
Action: Make the calling routine become NOINT when it removes the address

out by the free space manager. The block is outside the
range of free space management.
Action: Look through the dump. By looking at the stack you
should be able to determine who called for the releasing
of the block.

BUG.(HLT,RESBAZ,FREE,SOFT,<RELRES - Free block returned more than once>,
<<T1,BADADR>,<T2,CALLER>>,<
Cause: This is a free space problem. The caller is returning a block to
resident free space. The block being returned is already a released
block in the resident free space pool. Thus, the caller is either
returning the same block twice or has a completely random address which
is incorrect.
Action: If the problem persists change the BUGCHK to a BUGHLT. The caller
may or may not be the culprit. It is possible that some other

BUG.(HLT,RH1ICF,PHYH11,SOFT,<PHYH11 - Invalid channel function>,,<
Cause: This BUGHLT can only happen on the 2020. The CHSTRT routine is
called to perform disk operations. On the call, Q1 is supposed to
contain a function code, and T2 is supposed to contain the value to
be used for a DATAO. However, -1 in Q1 denotes that T2 contains
the DATAO but that no function is to be done.
The BUGHLT will occur if T2 is 0, or if T2 is non-0 and Q1 is 0,
which can only occur due to some caller supplying CHSTRT with
bad arguments.

Cause: The routine to unlock a connection block has found an inconsistency
in the lock count. Earlier in the routine, the current count was 1.

Cause: SCA has been notified of a new system coming online. It tried
to allocate two buffers to be used for connection management, and

BUG.(HLT,SEC0RL,FREE,SOFT,<RELRES called from section 0>,<<T4,PC>>,<
Cause: A routine in FREE that releases free space was called from section
0 with an address of free space in a non-zero section. This probably
means that the caller should be running in a non-zero section, since
any attempt to reference the free space would fail.
Action: It is essential that any code that references a non-zero section
run in a non-zero section. The long-term solution is to study the
entire stack and make all the code run in section 1. For the short
term, it may be possible to insert an EA.ENT at the beginning of

BUG.(HLT,SERFRK,SYSERR,HARD,<SERINI - Cannot create SYSERR fork>,,<
Cause: The cause of this BUGHLT is that Job 0 was unable to create a
SYSERR fork. The specific JSYS that fails is the CFORK JSYS,
and the dump should have the reason for the failure. Look at
LSTERR to determine the reason the CFORK failed.
Action: The action needed to remedy this problem depends on the error returned
by CFORK. Look at that code and try to determine how to
undo what it is complaining about.

BUG.(CHK,SERGOF,SYSERR,HARD,<SETOFI - Cannot GTJFN/OPEN SYSERR file>,,<
Cause: The SYSERR fork failed to open the ERROR.SYS file for output.
SYSERR first attempts to get a JFN on a currently existing version

BUG.(HLT,SHRNO0,PAGUTL,SOFT,<DESPT - Share count non-zero>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. The caller is expected to have ensured
that the SPT slot is no longer in use. The BUGHLT indicates
that the share count for the SPT slot is non-zero, indicating
that some process is using the slot.

BUG.(HLT,SKDCL1,SCHED,HARD,<Call to scheduler when already in scheduler>,,<
Cause: Code running in scheduler context has attempted to dismiss, block
or page fault thereby trying to enter scheduler context again.
This might result from an unexpected page fault or faulty logic,
i.e. the code doing the dismiss was not expected to be run
in scheduler context.
>)
BUG.(HLT,SKDFKS,SCHED,HARD,<Illegal scheduler action while fork context
setup>,,<
Cause: The scheduler was about to perform an action that requires that no fork
context is setup. The monitor found that FORKX was non-negative which
indicates that fork context was setup.
Action: Change the monitor to call DISMSJ before calling the routine or
move the call to a more appropriate place. CLK2 always forces
DISMSJ and is usually a good place for periodic actions.
>)
BUG.(HLT,SKDMPE,APRSRV,HARD,<MPE in scheduler or PI context>,,<
Cause: A page fault occurred indicating an AR or ARX parity error
while the monitor was processing an interrupt or running

BUG.(HLT,SKDPF1,APRSRV,SOFT,<Page fail in scheduler context>,
<<T1,UPTPFW>,<T2,TRAPPC>,<T3,TRAPFL>>,<
Cause: A page fault occurred while the monitor was running in scheduler
context and the page fail word did not indicate a "hard"
failure. This is probably a software bug because the
scheduler executes only resident code. One cause of this failure is a
reference to a piece of swappable code or data that is not currently in

process normally receives an error return when this happens.
However, in this case the error occurred in the scheduler,
and there is no recovery.
Data: PC - PC of last MUUO. This may or may not be relevant
LSTERR - Last error code. This may indicate where error was

BUG.(CHK,SMGFUL,PAGEM,SOFT,<Can't swap multiple pages (drum is full)>,,<
Cause: The monitor is attempting to swap a group of core pages to the

of drum assignments should insure that there are always a
few pages available for "critical" assignments such as
this case. It is possible that some user program could overtax
the normal reserves and cause this failure.

BUG.(INF,SPRZR1,SYSERR,SOFT,<SEBCHK - SPRCNT went to zero>,,<
Cause: The SYSERR fork keeps a running count of the number of entries made
on the error file in SPRCNT. This count is continous over system

overflowed its one word value.
Action: None. The count has wrapped around, probably legitimately, and will
be reset to zero.
>)
BUG.(INF,SPRZRO,JSYSA,SOFT,<SETSPR - SPRCNT was set to zero>,,<
Cause: SMON% function .SFSPR (Set count of SPEAR entries output) was
called with a value of 0. This indicates that the monitor could not
get the running count of the number of SPEAR entries output from
either the dump file or ERROR.SYS.
SPRCNT is a cell which should contain the running number of SPEAR
entries made in the ERROR.SYS file over the life of the system.

BUG.(HLT,SPTFL1,PAGUTL,SOFT,<SPT completely full>,,<
Cause: The monitor is attempting to assign to a process a slot in the
non-OFN part of the SPT tables. Normally a linked list points to
the free slots. The header is now 0, indicating either that there
is confusion in the list or there is not available slot. The
monitor normally protects against this event by refusing to
assign additional SPT slots when the available number falls
below a fixed minimum. This BUGHLT indicates a failure of
this mechianism or corruption of the free list.
>)
BUG.(HLT,SPTFL2,PAGEM,SOFT,<SPT completely full>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file page that is not
already shared. The code is going to create an entry for the
file page in the SPT so that the destination can have a
share pointer. The choice of a share pointer over an indirect
pointer was made because the count of available SPT slots
exceeded a threshold. The BUGHLT occurred because the head
of the queue of free SPT slots contains a zero, indicating
that there are no free slots. This means that there is an
inconsistency in the monitor's data.
>)
BUG.(HLT,SPTPIC,PAGEM,SOFT,<SWPIN - SPT page already in core>,,<
Cause: A routine has been called to swap a page into core. The id for
the page indicates that it is a page table. The BUGHLT occurred
because the SPT entry for that page table already contains a core
address.
>)
BUG.(HLT,SPTSHR,PAGUTL,SOFT,<UPSHR - SPT share count overflow>,,<
Cause: The share count for an SPT slot (not an OFN) has been
incremented beyond the maximum value. This can be caused
by a pathological program.
>)
BUG.(CHK,SPWRFL,APRSRV,HARD,<Spurious power fail indication>,,<
Cause: A power-fail indication was given and the monitor has
executed its sequence for an orderly power-down. The machine
is still running after a long delay, so the monitor has
declared the power-fail warning to be a mistake. The system
will restart as if power had failed.

BUG.(CHK,SRQBAD,SCHED,HARD,<SCDRQ - Bad call to SCDRQ7>,,<
Cause: SCDRQ7 was called with a function it does not know about.
Action: Fix the call or fix SCDRQ7 to know about this function.
>)
BUG.(HLT,STRBAD,PAGUTL,SOFT,<ASOFN - Illegal structure number>,,<
Cause: A routine was called to assign an OFN (index block). The
caller provided a structure number that was invalid, either
because that number can never exist or because it does not
exist now.
>)
BUG.(CHK,STROFF,MSTR,SOFT,<OFN on mounted structure but STRTAB entry is zero>,,<
Cause: The SPTH table has the N+1 through NOFN number of files on a particular
structure marked as being on a mounted structure, but the STRTAB entry
for this structure is zero.
Action: The table should be corrected in a few seconds. However, there may
be flurry of bugchks, depending upon how many files are open on the
structure. If the bugchks persist, check for improperly dismounted
or spun down drives.
>)
BUG.(HLT,STRTER,MEXEC,SOFT,<Fatal error while processing previous startup
error>,,<
Cause: When a software channel 34 or 35 interrupt happens on fork
0, the monitor transfers control to the routine specified in
MONBK. This address will often be the starting address of
JB0INT. JB0INT handles errors in fork 0. While JB0INT is doing its
error recovery, it sets MONBK to J0EMER, so that this STRTER BUGHLT
will occur if another error happens during JB0INT execution.
>)
BUG.(HLT,STZERO,FILINI,HARD,<FILINI - STRTAB entry for PS is 0>,,<
Cause: This will happen if the code that is supposed to set up
the STRTAB entry for PS: was never executed. If this happens,
some data has been corrupted.

BUG.(CHK,SWPPSB,PAGEM,HARD,<Swap error in PSB page>,,<
Cause: A hardware error occurred when the monitor was reading or writing
a page in a process's per-process area to or from the swapping space.
The monitor will continue to run in an attempt to update the BAT
blocks, but will crash with a SWPXXX bughlt as soon as the disk has
been updated. If the monitor is unable to update the disk (in the case

Cause: A hardware error occurred when the monitor was reading or writing
a page from the file system or swapping space. The monitor is
unable to identify the owning page table.
The monitor will continue to run in an attempt to update the BAT
blocks, but will crash with a SWPXXX bughlt as soon as the disk has

BUG.(CHK,SWPUPT,PAGEM,HARD,<Swap error in UPT, or PSB>,,<
Cause: A hardware error occurred when the monitor was reading or
writing a special page (PSB, JSB or user page table) in
the swapping space.
The monitor will continue to run in an attempt to update the BAT
blocks, but will crash with a SWPXXX bughlt as soon as the disk has

BUG.(HLT,SWPXXX,DSKALC,HARD,<Unrecoverable swap error for critical page>,,<
Cause: The monitor had a swap error for a PSB, PT, PTP, or UPT.
At the time of the error, a BUGCHK reported the problem,
and allowed the system to continue to record the error in
SYSERR, and rewrite the BATBLOCK.
>)
BUG.(INF,SYENCD,SYSERR,SOFT,<SYSERR - Missing code for error type>,

BUG.(CHK,TRPSIE,SCHED,HARD,<TRAPSI - No monitor for trapped fork>,,<
Cause: A fork executed a JSYS that was marked as trapped, but there is no
fork monitoring this JSYS trap.
Action: Ignore the JSYS trap.
>)
BUG.(HLT,TTBAD1,MEXEC,SOFT,<Bad device designator for terminal at ATACH2>,,<
Cause: The call to CHKDES failed. This should not happen, since the terminal
number involved comes from Q3, which is either the number of terminal
controlling the job, or a user-supplied terminal number from the user's
AC4. If a user-supplied number is being used, it was range-checked by
comparing it to NLINES. If it is the number of the controlling
terminal, the job was already verified to be attached somewhere, so
this BUGHLT should not occur.
>)
BUG.(HLT,TTDAS1,SCHED,HARD,<HLTJB - Unable to deassign controlling terminal>,,<
Cause: The monitor is killing the last (top) fork in a job and is trying to
deassign the job's controlling terminal. The attempt has failed for an
unexpected reason (one that will not be corrected if the fork waits a
while). This indicates inconsistency in the monitor's data base.
>)
BUG.(INF,TTFSMS,MEXEC,SOFT,<Failed to send system message>,,<
Cause: The most likely reason for this failure is that RSX20F cannot
complete the previous TTMSG request. Typically this is caused by a
hung DH11 line, but could be a software bug as well.
>)
BUG.(HLT,TTICN0,TTYSRV,SOFT,<GTTCI - No buffer pointer but count non-zero>,,<
Cause: At TCI0 (get a character from the line's input buffer) the pointer to
the dynamic data base for the line was 0. This could either be a
coding error or the resident table containing the pointers was
clobbered.
Action: Look at the dump. The stack should indicate which routine called
TCI0 without the pointer.

BUG.(CHK,TTILEC,TTYSRV,HARD,<TTSND - Unrecognized escape code>,
<<2,TDB>,<3,TTY>>,<
Cause: An unrecognized function escape character was encountered in a TTY

BUG.(HLT,TTLOKB,TTYSRV,SOFT,<BAD TTY LOCK IN TTLCK>,,<
Cause: The monitor tried to lock a TTY line and discovered the lock
count was overdecremented.
>)
BUG.(CHK,TTNAC1,FILMSC,HARD,<Line not active at PTYOPN>,,<
Cause: STADYN was called to get the address of the dynamic data block for
a TTY line that corresponds to PTY. This BUG means STADYN returned
+1, indicating that there is no dynamic data block assigned for
that line. This should never happen.
>)
BUG.(HLT,TTNAC3,DSKALC,HARD,<CTY not active at FSIPBO>,,<
Cause: The monitor tried to write to the CTY, but the CTY was not available to
output a character. The line is not active.
Action: Call Digital Field Service.

BUG.(HLT,TTNAC4,DSKALC,HARD,<CTY not active at FSIPBI>,,<
Cause: The CTY was not available to read in a character.
Action: Call Digital Field Service.
>)
BUG.(HLT,TTNAC5,DSKALC,HARD,<CTY not active at FSIINI>,,<
Cause: While mounting the public structure, the monitor found it
had no CTY on which to output information.
Action: Call Digital Field Service.

but the line was inactive and had no block.
Data: TTYLIN - TTY line number
>)
BUG.(HLT,TTNAC8,DEVICE,SOFT,<Cannot assign terminal at DEVINI>,,<
Cause: The monitor could not assign a terminal to a job because
1. It failed to get resident storage.
2. The line is not fully active; it is okay for system messages
and sendalls. Need a CNTRL/C on line.
3. Of a programming error.
>)
BUG.(HLT,TTONOB,TTYSRV,SOFT,<GTOCHR - No buffer but count non-zero>,,<
Cause: At TTSND7 (send a character to a line) the pointer to the
line's data base was 0. This is either a coding error or the resident
table containing the pointers was clobbered.
Action: Look at the dump. The stack should indicate which routine
made the call without a pointer.
>)
BUG.(CHK,TTQADX,TTYSRV,SOFT,<TTYSRV - Unknown function requested>,<<T3,ADR>>,<
Cause: TTQAD has been called with a routine address that is not
in its local table of known routines.
Action: Look at the stack to find the call to TTQAD. Then find
the name of the routine being passed and add it to the TQFNT
table.

BUG.(CHK,TTULKB,TTYSRV,HARD,<Bad TTY unlock in ULKTT>,,<
Cause: The monitor tried to unlock the TTY and it was already
unlocked.

BUG.(CHK,TTYBBO,TTYSRV,HARD,<TTYSRV - Big buffer overflow>,,<
Cause: The buffer for incoming TTY characters was full. (The character
was discarded and the line XOFFed.)

BUG.(CHK,TTYNTB,TTYSRV,HARD,<Ran out of TTY buffers>,,<
Cause: TTGTBF was called to assign and set up TTY buffers but TTFREC
indicates that there are no buffers available.
>)
BUG.(INF,TTYSTP,RSXSRV,HARD,<Line has been shut off because of excessive
input rate>,<<T2,LINE>>,<
Cause: A terminal line on RSX20F is generating input at an excessive
rate. It is being shut off for 3 seconds by having its input
speed set to 0. This can result from a noisy line which has a high
input baud rate. If an EIA line, it may be too long and so picks
up electrical noise.
Action: This problem can be prevented by eliminating the noise or reducing
the input speed.
>)
BUG.(HLT,TVTNTV,TTYSRV,SOFT,<TVTCHK called with non-TVT>,,<
Cause: TVTCHK was called to determine the status of a TVT line, but the
line number provided by TCP is not a TVT line. TCP should never
call TVTCHK with a non-TVT line.
>)
BUG.(HLT,TWQNUL,PHYSIO,HARD,<PHYSIO - PWQ OR TWQ was null at a seek or
transfer completion>,,<
Cause: When I/O completed on a unit, either OFFTWQ or OFFPWQ was called to
remove the current IORB from the position wait queue or the transfer
wait queue. The error occurred because the queue was empty.
>)
BUG.(HLT,UIONIR,PHYSIO,HARD,<UDSKIO - No IORB for NOSKED fork>,,<
Cause: The routine UDSKIO was called to do special I/O for a fork,
and to do the I/O it uses one of a group of preallocated IORBs.
There were no free IORBS left, and the fork could not
block because it was NOSKED.
>)
BUG.(CHK,ULKBAD,TTYSRV,HARD,<Unlocking TTY when count is zero>,<<T2,TTYLIN>>,<
Cause: A call has been made to ULKTTY to unlock a terminal but the lock

Data: LOCK - Lock index and flags
CALLER - Caller's address
>)
BUG.(CHK,ULKSTZ,FUTILI,HARD,<Overly decremented structure lock>,,<
Cause: ULKST1 was called to unlock a structure but the lock count was
already zero.
>)
BUG.(CHK,UNBFNF,SCHED,HARD,<Fork not found>,,<
Cause: This BUG can be caused in one of three ways:
1. UNBLK1 was called to unblock a specific fork and the fork was
not blocked.
2. UNBLK1 was called to unblock a specific fork and the fork was
not on the wait list it claimed to be on.
3. RECONC was called to transfer a fork from one wait list to
another, but the fork was not on the list it claimed to be on.
>)
BUG.(HLT,UNFWSS,PHYSIO,SOFT,<Unit not found creating SDB for structure>,,<
Cause: The routine SETSTR was called to build an SDB for a structure.
One of its arguments is the channel, controller, and unit numbers
of a unit which had already been known to exist. But when the
routine CHKCKU was called to find the UDB of the unit, the routine
failed to find the unit.
>)
BUG.(HLT,UNPGF1,APRSRV,HARD,<MEMPAR - Parity error during mem scan>,,<
Cause: A page fault occurred while the monitor was scanning memory
looking for an MB parity error. The monitor expects to cause
such a fault when it references the bad word in memory. However,
the PC indicates that the error occurred somewhere other than
in the instruction that is expected to fail. The monitor has printed
a description of the problem on the CTY. A SYSERR block has been
created and will be placed in the SYSERR file when the monitor is
rebooted. If the memory scan has detected any errors, the monitor has
printed a description of them on the CTY, too.
>)
BUG.(HLT,UNPGF2,APRSRV,HARD,<Unknown page failure type>,,<
Cause: A page fault has occurred and the page fail word indicates
a "hard" error. The monitor has read the type of failure from
the page fail word and one of the following is true:
1. The hardware is never supposed to generate the code.
2. The code is valid, but the scheduler is running, and this
code should never be generated from scheduler context.
>)
BUG.(CHK,UNPIRX,SCHED,HARD,<UNPIR - No PSI in progress>,,<
Cause: UNPIR was called to leave PSI context but there was no PSI in
progress.
Action: Continue.
>)
BUG.(HLT,UNXMPE,APRSRV,HARD,<PFCDPE - Unexpected parity error trap>,
<<T1,PFW>,<T2,PADR>>,<
Cause: The monitor was processing an AR or ARX parity error when
a second error occurred. The monitor retries the reference
that caused the original error and is prepared to handle
a second error. However, the BUGHLT indicates that the
error occurred during the processing but not during the retry.
Data: PFW - Page fail word
PADR - Address of page fail
>)
BUG.(INF,USGHOL,MEXEC,HARD,<Lost page(s) in usage file>,,<
Cause: This BUGINF indicates that the first free page in the USAGE file as
reported by FFFFP% is not the last page in the file. This means
that the file has holes in it, or lost pages.
Action: The USAGE must be repaired.
>)
BUG.(HLT,UXXCKP,MEXEC,SOFT,<Couldn't create checkpoint file>,,<
Cause: The file PS:[ACCOUNTS]CHECKPOINT.BIN.1 could not be referenced
for one reason or another. The code first attempts a GTJFN (GJ%PHY,
GJ%OLD) and an OPENF (OF%RD,OF%WR,OF%RTD), one of which must fail
for UXXCKP to be a possibility.
After the above GTJFN or OPENF has failed, then a GTJFN (GJ%PHY,GJ%NEW)
is attempted. If this succeeds, then UXXCKP will occur if a failure
happens on one of the following: the subsequent OPENF (OF%WR,OF%RD),
the call to ASGSWP to allocate CKPSIZ words, or the SOUT writing
CKPSIZ words to the checkpoint file.
If the GTJFN (GJ%PHY,GJ%NEW) fails, then another GTJFN (GJ%PHY,GJ%DEL)
is attempted, and its failure will cause UXXCKP. If this GTJFN
succeeds, however, then a CHFDB (turning off FB%DEL to undelete the
file) is done, and its failure will also cause UXXCKP.
Action: Use EDDT to patch the system so that you can bring up the system
without the checkpoint file being referenced. Then get the checkpoint
file into a state such that none of the above failures will occur.
>)
BUG.(CHK,UXXCL1,MEXEC,HARD,<Unable to create new usage file>,<<T1,ERRCOD>>,<
Cause: The USAGE file could not be created. This error will occur if a JFN
cannot be obtained on the file or if it cannot be opened.
Data: ERRCOD - JSYS error code
>)
BUG.(CHK,UXXCL2,MEXEC,HARD,<Unable to open new usage file>,<<T1,ERRCOD>>,<
Cause: This bug indicates that the USAGE file could not be opened. This
will occur if a JFN cannot be obtained on the file or if the file
cannot be opened.
Data: ERRCOD - JSYS error code
>)
BUG.(CHK,UXXCL3,MEXEC,HARD,<Unable to close usage file>,,<
Cause: This bug indicates that TOPS-20 could not CLOSF the USAGE file.
This bug is highly unlikely unless the JFN has been lost.
Data: ERRCOD - JSYS error code
>)
BUG.(HLT,UXXCRE,MEXEC,SOFT,<Cannot create usage file>,,<
Cause: If the GTJFN (GJ%PHY,GJ%OLD) or the OPENF (OF%RD,OF%WR,
OF%RTD) on the file pointed to by CKPFIL (PS:[ACCOUNTS]
CHECKPOINT.BIN.1) fails, then another GTJFN (GJ%FOU) and OPENF
(OF%WR) is attempted in order to create a new checkpoint file.
If these latter GTJFN and OPENF fail, the UXXCRE BUGHLT occcurs.
Action: Analyze the error code from the failing JSYS, and fix the
checkpoint file so that the error does not happen.
>)
BUG.(CHK,UXXFAI,MEXEC,HARD,<USAGE JSYS failure>,,<
Cause: The monitor attempted to perform a USAGE% call to log either a
login, logout, or session entry and it failed. There is no
reasonable explanation for the failure of this JSYS call.
>)
BUG.(INF,UXXFIT,MEXEC,HARD,<Checkpoint file not in correct format for this
system, rebuilding...>,,<
Cause: The PS:<ACCOUNTS>CHECKPOINT.BIN file is not in the correct format
for this monitor's configuration. This can occur if the value of
NJOBS has changed from the previous monitor or if the size of the
checkpoint records has changed. This BUGCHK can be expected if the
monitor has been upgraded from 5.1 to 6.0 or 6.1.
Action: TOPS-20 will rebuild the CHECKPOINT file.
>)
BUG.(HLT,UXXILL,MEXEC,SOFT,<USGMES - Illegal function code>,,<
Cause: The USAGE JSYS causes entries in the usage queue. Each
entry has a dispatch offset which is used by USGMES as an index into
a vector for calling the appropriate support routine.
If the dispatch offset is too large, this BUGHLT occurs. Since the
monitor itself is creating the entries in the queue, such a mismatch
should never occur.
>)
BUG.(HLT,UXXMAP,MEXEC,SOFT,<USGMAP - Call to JFNOFN failed>,,<
Cause: USGMAP wants to map a page of a file into FPG0 via SETMPG.
It calls JFNOFN to convert the JFN.PN atom to OFN.PN, which SETMPG
wants. If JFNOFN fails, this BUGHLT occurs. Some reasons that JFNOFN
will fail are: JFN is not associated with a disk file; JFN is not open;
attempt to create a new page table for a file that is not open for
writing; attempt to create a new page table for a directory file;
attempt to create a new page table for which there is no room on disk.
>)
BUG.(HLT,UXXOPN,MEXEC,SOFT,<Unable to open usage file>,,<
Cause: USGINI invoked OPENF (OF%RD,OF%WR,OF%RTD), which failed to open the

BUG.(CHK,UXXWER,MEXEC,HARD,<Write error in usage file>,<<T1,PAGE>>,<
Cause: A SOUT or UFPGS error occurred while trying to write to the USAGE
file. This indicates that there is a hard error in the file.
Action: The USAGE file must be repaired.
Data: PAGE - Page number in USAGE file
>)
BUG.(CHK,WRTBT4,DSKALC,SOFT,<ASOFN on bit table file failed>,<<T2,STRCOD>>,<
Cause: Could not assign an OFN for the structure bit table.
Data: STRCOD - Structure Unique Code
>)
BUG.(CHK,WRTCPB,DSKALC,HARD,<WRTBTB - Failed to backup ROOT-DIRECTORY>,
<<T1,STRCOD>>,<
Cause: The bit table is being written. The backup root-directory or
symbol table may not have been written, or there may not be
enough free space on the pack.
Data: STRCOD - Structure Unique Code
>)
BUG.(HLT,WRTLNG,DSKALC,SOFT,<WRTBTB - Bit table is a long file>,,<
Cause: The FDB for a file structure bit table has the FB%LNG bit set, which
says the file is a long file.
>)
BUG.(CHK,WSPNEG,PAGEM,HARD,<SOSWSP - WSP negative>,<<FX,FORK>,<T2,FKCSIZ>>,<
Cause: SOSWSP has been been called to decrement the working set size of
the current fork by one. In so doing, the working set size would
become negative. This indicates a problem with the monitor's
calculation of the fork's working set size since it should never be
negative.
Action: The working set size has not been decremented.
Data: FORK - Fork number
FKCSIZ - Current size of working set (RH of FKWSP)
>)
BUG.(HLT,WSSPNA,PAGEM,SOFT,<WSSFKP - Fork special page bad age>,,<
Cause: The monitor is swapping out all pages of a process. It is
trying to swap out one of the special pages (JSB, PSB, etc.).
The page should be in core and locked, but it is not
assigned (its age is LESS THAN PSASN).
>)
BUG.(HLT,WSSPNC,PAGEM,SOFT,<WSSFKP - Fork special page not in core>,,<
Cause: The monitor is swapping out all pages of a process. It is
trying to swap out one of the special pages (JSB, PSB, etc.).
The page should be in core and locked, but it is not in core.
>)
BUG.(HLT,XBLTAL,APRSRV,SOFT,<XBLTA asked to copy too much>,<<T1,LENGTH>>,<
Cause: XBLTA was called with a 'length to BLT' of more than one section.
It is unlikely that the caller really intended to copy this much.
Data: LENGTH - Number of words XBLTA was asked to copy
>)
BUG.(CHK,XBWERR,PAGUTL,HARD,<UPDOFN - Disk write error on XB>,,<
Cause: UPDOFO was called to scan an index block and write the image to
disk. This BUG indicates that there has been a disk write error on
the index block.
>)
BUG.(HLT,XSCORE,PAGUTL,SOFT,<CST too small for physical core present>,,<
Cause: A routine has been called to map a specified core page to a
specified virtual page. The BUGHLT indicates that the caller
provided a page number of a core page that does not exist.
(The number is too large). This BUGHLT can occur if a monitor
that is built for less than 256K is booted on a machine whose
memory exceeds 256K.
Action: If the monitor was built for less than 256K, and there
is more than 256K of memory on the system, rebuild the monitor
for the correct amount of memory.
