Has anyone ever seen this problem?

[JD Austin]

I have a new client that has a weird problem with their linux file server.
It is rebooting without warning several times a day.

Notice how it happened almost at the exact same time yesterday.

*Since it only had a 330W power supply and several extra fans in the case
I replaced the power supply with a 500W power supply last night.
The computer is plugged into a UPS.  Yesterday prior to getting a new
power supply I had them plug the machine directly into the wall to see if
it was the UPS causing it, the problem persisted.


I can find nothing in the logs that would indicate that hardware
is failing, they all look like this:

Oct 21 04:23:11 aflsdebprod -- MARK -- 
Oct 21 11:45:59 aflsdebprod syslogd 1.4.1#10: restart.
Oct 21 11:45:59 aflsdebprod kernel: klogd 1.4.1#10, log source = /proc/kmsg started.
Oct 21 11:45:59 aflsdebprod kernel: Inspecting /boot/System.map-2.4.18-bf2.4


Anyone had this happen to them before?
