fault detection

[Scott Prive]

You could have faulty memory. The memory test on starting the BIOS or any OS, is a very limited test. 

If you have a faulty memory chip, you increase the chances of "hitting it" by running some high-load benchmarks or system tests. 

These are disruptive to a production server, but cpuburn, memtest, and the Linux Test Project are all pretty rough on the kernel & hardware. If there is an intermittent problem, these could help you triage more quickly than waiting for the next crash event.

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
