Hi,
I have a small backup Server which runs on Debian 5.0 Lenny with all
available stable updates.
For one month now this Server wasn't running for more than 24 hours
because of problems which passes me by. I checked the syslog, messages
and kernel log and the only anomaly I could find was a segfault entry,
normaly immediately before the restart entry like this:
> Aug 10 06:33:16 LXL-CGN-01 kernel: [2041002.927632] perl[11972]:
segfault at 157040 ip b7d563a2 sp bf803470 error 6 in
libc-2.7.so[b7d40000+155000]
I thought it is a problem with libc and probably with the main memory.
But the last few days, the server freezes without that messages. Now the
last log entries look like this:

This looks to me like: "Nothing to do and then freeze without a loggable
reason". Does anybody has an idea what I can do to determine the problem?
The whole /var/log/messages can be found here:

I'd run mentest over the weekend, and if that doesn't show any
errors, boot from a Live CD and fsck the / (and, if separate, /usr)
partitions.
Also, check if the filters are clogged, and install a sensor package
to see if the CPUs are overheating.
BTW, you should really fix all those MTA errors, since all that
redundant crud is hiding any other problems.
