Hi,
The MCA files are not very conclusive and we were able to decode only that its a "External Bus error" that triggered all the MCA's.

----- Analyzing Logical CPU 12(12) BUS_CHECK[0] MOD_CHECK_INFO ---------------
Event:Logical CPU 12(12): Skt 0, Core 6, Thread 0: BUS_CHECK[0]: An external buserror (Logic Reset (ERROR[1]_N)) was detected. This indicates that an errorwas detected outside the processor core. Review the analysis of the uncore,I/O subsystem and CEC to determine the source of the external error.
// You would need to focus on I/O subsystem (IO cards) and see if any of those are causing the reset (isolate one by one and observe system stability).// If still issue persists, then please log a support case with HPE Support Team for further assistance.
Thanks.
