[mod.computers.vax] Unknown crashes in VMS V4.2

INGERSOLL@ISI-VLSIH.ARPA (Steve Ingersoll) (11/14/85)

	Has anyone seen crash dumps relating to the loginout program?
We have been getting INVEXCEPTN bugchecks on our 750's about once a day. The
program that is always running is LOGINOUT, and the address of the crash is
always the same. Examination of the crash shows the following on the stack

	4
	7FFE7D90	- Saved FP
	FFFFFFFD
	00000015	- Saved R0
	00000003	- Saved R1
	00000001
	00000005	- Argument count
	0000000C	- Exception type ( access violation )
	00000004
	00000014
	800B2B66	- Exception PC
	00560004

	Examination the exception PC shows the following instruction:
	BISB2	#05,14(R11)


	I have not submitted an SPR because I am not sure if it is a problem
with LOGINOUT or with some code that we run here. I am planning on looking into
the crash in more detail but thought I would try and see if somone else has
noticed the problem...

Here at Harvey Mudd we are also experiencing periodic system crashes
on a 750 ever since we put VMS 4.2 on it. The bugcheck is the same as
Steve's, but most of the time only the NULL job is running. There was
a crash once, however,  while LOGINOUT was running. I am still trying
to figure it out. If I find anything I will let you know, and if you 
figure it out please yet me know. Thanks.

PLEASE DON'T POST THIS!!! I MAY BE WRONG!

Please tell the guy from Harvey Mudd who didn't give a return a.d. that
he should try keeping monitor running on one terminal.  I saw a Vax 11-780
with a cache board problem that crashed regularly when nothing was going
on, and only when nothing was going on.
