Re: Server crashing, no explanations
Have you tried disabling hyperthreading in the BIOS? I had the same problem with a herd of dell 2850s and the only fix under the conditions you describe seemed to be to disable the hyperthreading.

Hi Tobias, Yes the plan is the next time it crashes is to check BIOS, unfortunately I need to get hosts to do this as I can't physically access the machine at this point, but they have some KVM like switch attached to it.

Hi Mark, I'm guessing there's not a compatible chip on the motherboard for both of those items. Its a DELL server and unfortunately we only actually have one disk on it at the moment, so there's no RAID (which is also worrying :( ) Full memory checks have been on in the past and never reported any errors at the time. May be worth switching back on I guess.
