need help with FATAL error in unix 3.2u

[George Bogatko]

Sounds to me like memory chip problems.  If you have memory diagnostics,
run them.  If you don't, then if you can remove the chips, move the
chips in the low addresses to those in high address's, and vice-versa, and
see if your problems go away.  If they do, then memory chips was indeed
your problem. Now you'll have to determine which ones. 

If not chips, then ?????
