May 23, 20197 yr Hello. I logged into my server today to do something and noticed that Fix common problems was reporting "Machine Check Events detected on your server". I tried to look into the log file, however I am not sure what I am looking for. I have attached the diagnostic zip file, any help in figuring out what is happening would be greatly appreciated.

May 23, 20197 yr May 10 17:34:23 unraid kernel: [Hardware Error]: Corrected error, no action required. May 10 17:34:23 unraid kernel: [Hardware Error]: CPU:8 (15:2:0) MC4_STATUS[-|CE|MiscV|-|AddrV|-|CECC]: 0x9d384406001c011b May 10 17:34:23 unraid kernel: [Hardware Error]: Error Addr: 0x0000000001154f14 May 10 17:34:23 unraid kernel: [Hardware Error]: MC4 Error (node 1): L3 data cache ECC error. May 10 17:34:23 unraid kernel: [Hardware Error]: cache level: L3/GEN, tx: GEN, mem-tx: RD Which means that the L3 Cache on your CPU is possibly going bad. May just be a result of living on an Indian Burial Ground and a one time thing, but if it continues, your CPU is shot.
May 24, 20197 yr Author Sh**, just upgraded the CPU's. hope it is just a one time thing, how do I tell which one is having the issue, there are 2 processors on this board.
May 24, 20197 yr 1 hour ago, DocLove said: just upgraded the CPU's. Perhaps there is a bad connection to one of the CPUs. If it continues I'd remove and replace both, check the sockets and CPUs very carefully with a good light and a magnifying glass, or take crisp closeup photos from a couple angles, magnify and examine. 1 hour ago, DocLove said: how do I tell which one is having the issue, there are 2 processors on this board. If the motherboard logging isn't helpful, I'm guessing the only way to tell would be to run with only one CPU, and swap it out with the other CPU after a period of time.
May 25, 20197 yr Author Thanks for the info, If it continues I will do as you suggest. I hope it was just a one off.
