Server Lockups / random errors. Diagnostics attached

[bphillips330]

I have been having odd things happen over last week or two to my server.  Can't narrow it down.   

 

Seems to work for 2-3 days.  Then come down in the morning and it is not able to be reached.   Sometimes I can ping it, and it responds.  But webgui is not accessable.   Eventually just hard boot the server and it works again for couple days.  

Now weird thing is.   None of my shares are showing up.   Server is there.   ALL the drives are spun down.  Even the parity drive is spun down.   So I clicked spin everything up.   Still could not get to a share.   So I clicked on share folder.   Nothing showing there.  

 

Not sure if it is my cache drive.  Not terribly old. EVO 860 1tb ssd.   See weird stuff in the log.   I wiped and started the cache drive over last week.   Format and all.   then  did a restore from app data.     

 

I was able to pull a diagnostics before I just rebooted.  Please help.

Btrfs is detecting checksum errors on cache, this is usually from bad RAM, run a memtest, also make sure RAM isn't overclocked, it's known to corrupt data in some Ryzen systems.

Wierd.   I will check that.  I have 4 memory chips.   3200 mhz.  I have the mother board clocked at 3200 (the same speed as the ram)  Wonder if that is the issue?

4 Dimms should run at max 2133 or 1866 depending if single or dual rank.
