Hi everyone,

After a few hours of running, my server crashes. It stops working, and I have to turn it off and on again for it to work. It will operate for a few hours and then crash again.

I checked the logs but couldn't identify the problem. Can someone please help?

The syslog in the diagnostics is the RAM version that starts afresh every time the system is booted. You should enable the syslog server (probably with the option to Mirror to Flash set) to get a syslog that survives a reboot so we can see what leads up to the problem. The mirror to flash option is the easiest to set up (and if used the file is then automatically included in any diagnostics), but if you are worried about excessive wear on the flash drive you can put your server's address into the remote server field and log to a share instead.

I have attached the log file. I believe this one will contain multiple crashes

syslog-192.168.0.10.log

Probably unrelated, but why do you have system share set to be moved to the array? Ideally, docker/VM related shares appdata, domains, system should have all files on cache or other pool, with nothing on the array. Arguably, system is the most important of these to have on fast pool.

You have a number of segfaults in the logs. Have you done memtest recently?

Thanks for pointing this out to me. I fixed it.

I ran the memtest, and it passed without any errors

How long did you let it run?

I ran the one supplied with unrid ver 6.2, and it passed. Now I am running the latest version 8. So far, it pass 41% without errors

memtest86+ v8 passed as well; should I leave it running until it finishes? I know it will take a long time to complete the full test, as I have 64GB of RAM. I left this one running for 4 hours. I did not show any errors.

14900K is one of the most affected models by the Intel 13/14 gen issue; look for a BIOS update; it can sometimes help if the CPU is not too far gone.

BIOS is up to date. I have replaced this CPU under warranty last year

Doesn't mean it can't have issues again; I remember seeing a user who was on his 4th CPU.
