Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged

 

Posting my diag. log here as the plugin suggests and hoping someone could take a quick look.

I am not having any obvious issues at the moment. Everything seems to be working fine.

 

Thanks

Thank you. Are there any hints as to which of my 2 memory sticks may be failing? it's been a long time since I ran memtest86 but I remember it would take a long time to run.

I'm not 100% sure, but memtest86 could not show you that your ram has issue if it's ecc, since it corrects errors (if it's still able to do so); I had a similar problem in the past, errors related to ram, memtest was ok.

After changing 2 sticks of ram, which seemed to solve the issue, I found out that the issue came from one of the 2 cpus in my server.

So errors related to ram may come from other parts of the server.

My specific error was:
 

EDAC MC0: 1 CE memory read error on CPU_SrcID#0_Ha#0_Chan#3_DIMM#0 (channel:3 slot:0 page:0x1b2c39 offset:0x8c0 grain:32 syndrome:0x0 - area:DRAM err_code:0001:0093 socket:0 ha:0 channel_mask:8 rank:1)

Memtest can still work if there's an option on your BIOS to disable ECC.
