| >Does it correspond to a known bug ?
I don't know.
It looks like a null pointer was dereferenced, which could indicate
that you were out of virtual memory. Check your VIRTUALPAGECNT sysgen
parameter and your username's PAGE FILE QUOTA to ensure that you
are running in a supported configuration.
If your quotas look good, but your IMPM session had been up for a
very long time (weeks or days, depending on how much activity was
going on), it's possible that memory leaks exhausted all available
memory.
If you can rule those possibilities out, then read on.
Is this problem reproducible?
If so, we can use the debugger to find out what's going on.
If not, and you can remember (roughly) the actions
you took in the sesion that did crash, repeat the actions and
then use SDA to get a listing of the images. That will
at least tell us in which image the accvio occurred.
$ analyze/system
$ show process/image <process_name>

| Customer problem: he can make MCC crash at will.

file
crash with reserved operand fault
I have tried to duplicate on my work stations, and cannot, my VMS is
5.4-3. To duplicate the problem found a VMS V5.5-1 system running
BMS V1.2, MCC crashed at first try screen dump included:
