WebUI hangs / constant nchan memory error

[ksagle]

Hey,

 

I'm running Unraid 6.8.3 and am consistently running in to issues with the webui. The issue is resolved temporarily with a reboot, but always comes back a few days later. I've found a few threads about the same error but none of the suggestions worked, or we're not quite the same circumstances.

 

Symptoms are that the log volume fills up as syslong constantly logs the following errors. Clearing the older syslogs allows me to access some tabs (main/dashboard/share) while others partially load with the loading wave in the main frame, and the console spams ws errors.

 

 

During that time, syslog is flooded with errors like these:

I've attached the diagnostics file.

Does it do the same if you boot in safe mode?
