About 3 weeks ago I upgraded almost all (everything except storage drives) of the hardware in my Unraid server. Since then I have had problems with Unraid occasionally becoming completely unresponsive. My router still shows it as connected but I cannot connect to it nor to any of the docker apps I have running. A hard reset usually resolves the issue. On the old hardware, I have ran Unraid for years without this issue and the hardware upgrade doubled my RAM to 8GB. I ran a memtest on the RAM yesterday (8 cycles, no errors).

 

Initially, it seemed like this was happening when Plex was transcoding something to an external user. I had changed a Plex setting to transcode to RAM because I read that was a smart idea but maybe not.

 

Last night, my server appears to have gone offline (based on camera notifications) for like 20 minutes but recovered itself. I was able to get the syslog (attached). So that occurred Jan 10 around 02:00:00. Looking at the syslog, clearly it looks like Frigate may have been the culprit here but I'm not sure why.

 

Can anyone please help diagnose what may be causing this issue?

Perhaps your Realtek NIC?
