I'm pretty new to Unraid and have successfuly set up my server of the last week and imported all my data.

Over the last few days, the server keeps unexpectedly freezing forcing me to manually reboot the server which is not ideal. At first I thought it was simply due to running Immich face detection which was putting maximum load on my CPU. However, even after that has stopped and the server being under no load, the Unraid GUI freezes up and loses network connection.

I have looked through the syslog file and have seen a few lines similar to this:

Dec  1 16:19:01 Khilan-Server kernel: CPU: 2 PID: 9649 Comm: monitor Tainted: P        W  O       6.1.106-Unraid #1

It is always the CPU being tainted with different applications such as smartctl, monitor.

Also, under some server freezes, when I look through the syslog file, there doesn't seem to be any errors thrown up which is strange.

 

I have attached my syslog and diagnostics file if anyone more knowledge could help.

Have you done memtest?

Yes. I ran memtest when I first put together the server and ran overnight with no errors.

Since memtest is only definitive if it finds errors, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

After trying to disable individual Docker containers and still freezing up within hours, I ended up purchasing a new single 16GB DDR5 RAM stick to replace the one I had and now my server has been running for 3 days straight with no issues, even feeling a little more responsive.

I think I can safely put it down to bad hardware and nothing software/firmware side.
