CPU load is unusually high after upgrading Unraid Basic to latest version

[bthoven]

After upgrading Unraid Basic to the latest stable version (6.10.3), I found after running it for a while, the CPU load jumps to 80-99% continuously. Usually my CPU load should hovering around 20%+/-. I did not touch my applications since updating my unraid; only updated my dockers from time to time.

I usually have to restart my Unraid to solve the problem; but it will saturate my CPU again and again.

 

 

When I use htop command, I found these /usr/bin/php -q ..... processes uses over 100% CPU. In normal circumstance, I do not see these processes in the top ten list. What are these processes?

 

/usr/bin/php -q /usr/local/emhttp/webGui/nchan/device_list
/usr/bin/php -q /usr/local/emhttp/webGui/nchan/parity_list

/usr/bin/......

You should attach diagnostics to your next post in the thread. That will provide comprehensive set of actual information that others can use to possibly assist you.

Do you have multiple browsers open to your webUI?

When that incident happened, the webui took forever to load. I'll try the diagnostics function when it happens again. Do you know where the diagnostics log is actually kept, in case the webui won't respond and I still can ssh to my unraid server to view it.

If you use ssh then the ‘diagnostics’ command at the command line will put the results into the ‘logs’ folder on the flash drive.
