Subj: ZAP$MONITOR Problem
Hello, I have had the problem testing ZAP$MONITOR on the VAX4200 system as the
following report written by one of our Customer Support Enginner. Please
clarify the cause of it and let me know the way of getting over. I'll provide
it to the customer shortly. Prompt answer would be highly appreciated.
Best Regards,

FATAL BUG CHECK INTERMITTENTLY
Mf:0830-1730 Sat:0830-1230 Sun:0000-0000
-----------------------------------------------------------------------------
For the SSRVEXCEPTN, Unexpected System Service Exception. The current
process was ZAP$MONITOR and image was ZAP$MONITOR.EXE. The image called
SYS$EXIT system service, and then the process in Kernel mode was excuting
RET to return from the procedure. KRPs were used for storage local to
the execution of the procedure. System tried to get KRP. However, the
pointer to KRP lookaside list is invalid. That is, Access Violation to
insert KRP Lookaside List "INSQUE (R1),@04(R0)" in DEALLOCATE_KRP
routine in the SYSGETJPI module.
Internal and Data structure book mentions that the most common use
of the KRP is to store an equivalence name returned from a logical name
translation. So, I'd recommand to check the portion of handling logical
name in the application ZAP$MONITOR. Hope it to help you.
Best regards,
S.J
