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.

;INTERRUPT HANDLER BUGCHK AND TRY AGAIN
SEBINH: BUG.(CHK,SEBINT,MEXEC,SOFT,<Unexpected interrupt in SYSERR process>,<<ITFPC,ITFPC>,<LSTERR,LSTERR>>,<
Cause: An unexpected error has occurred in the process that handles
error logging. The error handler will attempt
to reinitialize the context and resume processing. The
stack may be examined for an indication of where the error
occurred.
Data: ITFPC - PC when error occurred.
LSTERR - Last error code in fork.

SEBOF2: 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
of the file. If that fails, it attempts to get a JFN for a new
version of the file. This BUG indicates that both attempts failed.

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
reloads and crashes. This BUG indicates that the count has
overflowed its one word value.
Action: None. The count has wrapped around, probably legitimately, and will
be reset to zero.
