Ucorrectable MCE on HP Proliant Dl 380 g9

Hi,.

Seem's the Hyperthreading or x2APIC technology is causing random reboot's.

After disabling them, 2 days under heavy load test without any reboot's.

With enabled nearly 11 reboot's with umce's per day.

Action Plan:

*I suggest you to update the SPP which will take care of all the driver/firmware to the latest version.

SPP: http://h20564.www2.hpe.com/hpsc/swd/public/detail?sp4ts.oid=5177954&swItemId=MTX_3f6b4074ed734dc3baf007612d&swEnvOid=4103

*need to configure memory as per configuration rules

*Swap DIMMS  with know good parts( same Hp Sapre number) and check

*replace processor 1 with HPE recommendation & check  (It seems like a Processor 1 failure)
