I had this problem and called Ultrix support. They send me a patch
tape for Ultrix 2.0 

The patches are suppose to fix the following problems:
-------------------------------------------------------
Major and minor numbers going to 0,0 in the /dev directory.
panic grele's
panic kmfree bad dealloc
panic glock
panic segmentation fault
panic MUNLOCK
tmscp device driver problems
panic PFCLEAR (vmem panics)
panic gfs_unlock
de# buffer unavabable
The biod data corruption problem
Some flow control problems within the device driver and hanging of
processes in the drivers.
Number of dmz's
ccr hangs
Named pipes causing segmentation violations.
-------------------------------
Warning - this patch was suppose to keep the old *.o files
but didn't for some reason I don't understand.
(The script should set $path and not read .cshrc - perhaps that
is why it didn't work in my case).
----------------------------------------------------
Now for the Bad news - The system is still crashing. But in a
different location! Ultrix support is working on it.

I admit I am puzzled why my system worked fine for months and then
crashed 8 times in one day. No apparent hardware problems.
