DUMP: SIGSEGV() ABORTING!

[Farhad Shakeri]

Hi  We have found a very strange problem on only one of our
3100s (mine) runing ultrix (3.1c).

Dump fails almost immediately after it starts by this error:

  DUMP: SIGSEGV()  ABORTING!
  Illegal instruction (core dumped)

This problem started about 2 weeks ago and we can't figure out
why.  I thought I had a bad binary or corrupted filesystem
but those looked fine when I compared (sum) them to other 3100s
and they looked fine and passed fsck!  

dump failed in all forms of test, even to /dev/null .

anyway if anybody has seen this sort of problem please let me know.

I am going to convert to 4.0 soon but I would like to solve this
mystery.

Also  can this be a hardware problem?

Thanks a lot.
