	 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.

	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.

Cause:	An unexpected error has occurred in the process that handles error

SEBOF2:	BUG.(CHK,SERGOF,SYSERR,HARD,<SETOFI - Cannot GTJFN/OPEN SYSERR file>,,<

Cause:	The SYSERR fork failed to open the SERR:ERROR.SYS file for output.  The
	SYSERR fork 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.

Action:	There is a problem with writing the SERR:ERROR.SYS file.  Make sure
	that the file structure is in good shape, has enough space available,
	and that the directory is in good shape.  If there seems to be a lot of
	disk problems, have Field Service check out the hardware.

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:	No action is required.  The count has wrapped around, probably
	legitimately, and is reset to zero.
