One more thing I remember: Doing a “ps –welf” shows that the fileserver
processes are waiting on "schedu" or "rt_sig", but this never changed as it
does in fully operational servers.

Note also: "bos shutdown" only killed some fileservers and all other
afs-server-processes besides the bosserver.

But how can I get it? Is it really a memory problem? The Linux box itself
seemed to be fine. There were no kernel messages regarding our problem.

Even "kill -KILL" doesn’t work. So "kill -SEGV" doesn’t trigger the usual
core file production.
