Yesterday we had one of our servers go down and after it was displaying this error (seen in title). It hasn't crashed since but I've been unable to find a cause. I checked the event logs and nothing prior to the crash. I do have a event ID 1604:
Processor sensor detected a failure value
Sensor location: CPU1
Chassis location: Main System Chassis
Previous state was: Unknown
Processor sensor status: Presence detected, IERR
Not sure if this helps at all but let me know if I can provide more information.
Thanks for your help
