fault detection

[FRamsay at castelhq.com]

Does anyone know of any tools to help figure out why a box rebooted?  One
of our client boxes rebooted
over the weekend for no apparent reason.  The client claimed there was no
power outage, and a quick look
over the logs verifies the UPS didn't shut the computer down.  Also I
didn't see a shutdown or reboot request
in /var/log/messages.  So what tools do people use to figure out why a
Linux system crashed?

the system is running Redhat 7.2  kernel 2.4.9-13
