I don't have any VM running. I noticed that one of the process (shfs) may be the issue. Also, the UI don't report anything in progress (parity check, etc.).

The system seems to behave normally, but I find it odd to have this constant CPU hog. Before rebooting/restarting, I wanted to ask the community about the issue and maybe identify the root cause. I searched for shfs in this forum, but I did not find obvious solution/explanations/diags.
