re. Problem with SS1

[Lewis E. Wolfgang]

Isidore reports a SparcStation 1 crashing with /usr/adm/messages muttering
something about "BAD TRAP" and "Data fault".

I have seen similar problems on one of our SparcStations that was traced
to a bad SIMM memory module.  For some unknown reason the memory error is
not trapped and reported as a memory problem, violating in the process,
Wolfgang's Principle of Least Astonishment!

Good Luck,
