December 25, 20187 yr Hi there, I searched the forums for my problem already but I couldn't find something related. I've got a command running, that eats up my CPU but I can't figure out where it comes from. The command is called "sh" and it should be related to any docker because it stays after stopping all dockers and before starting any docker after rebooting. Here is a screenshot of htop. The command fluctuates between 0 and nearly 100% CPU usage... Does anyone know if this is an plugin or something? Thanks in advance.
December 25, 20187 yr ps -auxf or the following if the above expands too wide to be seen on your terminal screen, and try to find the 'sh' process by process id and see what process tree it belongs to. ps -axf Edited December 25, 20187 yr by BRiT
December 25, 20187 yr If you track it up to some command "docker-containerd-shim" you can determine which exact docker container it is by matching container id prefixes. Notice how "9e837294036f" matches between the output of Docker Process and the overall Process output: ps -axf 13248 ?

December 28, 20187 yr Author Thank you for your answer but the CPU usage went away by itself. If this behaviour reappeares I will use your commands to investigate.

Just an perhaps unrelated followup, but this is the first Google-hit if you google "unraid sh high CPU". I did what @BRiT said and it look like sh were triggered by atd (scheduled job). It also had inotifywait (looks for updated files) in the same process tree. This lead me to the conclusion that the plugin "Dynamix Cache Dirs" may be involved somehow. I deactivated that plugin (since my problems with spinning up disks were solved) and the high CPU stopped. This was just a reminder for me to deactivate plugins I don't currently use.. This may help someone else coming to this seemingly dead thread. :)

Can confirm completely stopped after turning off folder caching from Dynamix Cache Dirs
