hi everyone!

I upgraded my UNRAID system from 6.10.3 to 6.11.5.

 

I found that every 20 seconds a process would randomly make a CPU thread occupy 100%. Continued for 7, 8 seconds back to normal, and repeated after 20 seconds. The process name is kworker/ : +events.

 

This situation does not exist in version 6.10.3.

 

Finally, I hope someone can give me some suggestions or ways to deal with this situation. Thanks in advance to everyone who has gone to the trouble of helping others in the community.

Please reboot in safe mode, disable docker/VM services and check if you still have the same issue.

I tested it, and the issue still exists in safe mode, even when The Array is not started.

 

See if this helps:

i am actually experiencing the same error, except my kworker is kworker/4:1+pm

I see the same thing, with or without safe mode, with or without the array started, and I have unplugged just about everything as well but no avail to me.

The article that @JorgeB pointed out, i have looked at it as well but i am not sure if the results that come out of that are the problem or not, i.e

I figured my problem. Mine was that my motherboard started to fail
