How to interprete MCA in the ASM event log

[samurai123]

Does anyone know how to interpret the MCA data?

One of our x365 server crashed with

I |SMI Hdlr |00151350 Processor MachineCheck Data a | reporting bank:0000 reporting APICID:0004 Status:8C000100 20140136 CR4:00000000
I |SMI Hdlr |00151351 Processor MachineCheck Data b b Address:00000002 CD23EE54 Timestamp:0007F36E 6E43125A
E |SMI Hdlr |00151200 MCA: Unrecoverable Error Detected 9 ProcID=01
E |SERVPROC |PFA Alert, see preceding error in system error log
I |SERVPROC |Initiating NMI


Thanks in advance.

Looks like memory---what OS? Are any of the Light Path Diagnostic lights lit? Recent patches, service packs, upgrades? I would definitely say either memory, cpu, or VRM---about a 90% chance of one of these three.

Thanks for your response.

It turned out to be problem with CPU. I really like to know about interpreting the MCA data "a" and "b".

Does anyone know how to?

Thanks

I believe you can look up the process ID (ProcID=1).
