We have an automated test rig in the lab, where we can network boot
machines which have been reported as troublesome. We can then run
memtest and stress tests on them for a long period.
I would advise running memtest on this machine for a day or so, then
some CPU heating stress tests.
Download Stresslinux http://www.stresslinux.org
Burn a CD and boot the machine from that, or if you have a PXE setup use
the PXE bootable version.
Boot into memtest first, and let it run for at least 24 hours.
Then boot up and run cpuburn
My gut feeling is a saggy powersupply. Either faulty or underspecced for
two processors plus lots of RAM.
I assume from what you say that in the syslogs there is nothing - the
system just halts for no reason?
