Intermittent unexpected reboots

Check for an event code that indicates a reboot. See the event log for the IBM Flex System Manager management software (if installed) or see the event log of the CMM to determine what actions might be required to resolve this issue. See IMM event log. Some correctable errors require that the compute node reboot so that it can disable a device, such as a memory DIMM or a microprocessor to allow the machine to boot up properly.
