Could someone help me understand what this process means and why it is taking up so much of my CPU usage (20-90% at times, 1-2% with more or less everything idle)

 

"/usr/local/sbin/shfs /mnt/user -disks 65535 2048000000 -o noatime,allow_other -o remember=0"

 

 

I'm having issues with high CPU usage associated with sonarr/radarr and figuring out this process seems to be a starting point. Any insight appreciated.

That process is normal and part of Unraid's user shares, you need to try and find what is causing it to use a lot of CPU, anything mapped or using /mnt/user/xxx will be using that process.
