Does anyone have any ideas on what might be causing a crash of Ultrix 4.2 
(just installed) on a 5000PX with the following message:
  
  bad c_page
  locks held by cpu 0
  print locks held by non-active process

This has happened twice in two days now. Both times I was running Saber-C,
it loaded my program and started it up, then right after I pressed a
button which leads to a couple of vfork()'s and exec's, the whole
system crashed, with the above message. But I have also run my program
under Saber successfully, both before and after the crashes. So it
does not seem to be a reproducible crash. There are also a number of other
users, so conceivably it has nothing to do with Saber.

By the way, after the first crash, fsck found *alot* of problems, and
ended up trashing several files (and probably more that we have not found
yet) including /etc/passwd.
