I see the only solution now: installation of Solaris :( Don't
want to, really, but it is our production server. Can anybody give an
advice, what can be a cause?
I've built two servers with identical hardware:
PPro-200 w/256k cache, 128M ram, AHA2940UW, Quantum Atlas II, S3
Trio 64/V+, 3C905.
One of servers is Linux one. It crashes every several hours. Just
system hang, with no messages in log (syslog is told to log *.debug) or
console. But last time it hang, console was full of scrolled messages
scsi0: queue full
I tried exchange every hardware with the second server, so I'm
pretty sure it is not hardware fault. Following is as much information as
I can imagine. Any ideas,
please?
