psutil.AccessDenied: psutil.AccessDenied (SOLVED!)

[SoMoney]

UBUNTU Server here (3950x w/64Gb)

I'm seeing these permission denied messages in my logs that's stopping my manager service.

I've verified every dir, subdir, file, temp, and destination folder is owned by my chia user and group.

I've even tried re-installing Swar-Chia-Plot-Manager with same results.

Once the stagger_minutes: time hits, manager.py launches a new plot but then subsequently stops with this psutil.AccessDenied.

Still digging into the root cause. I know if I run manager.py as root this would probably go away, but I figured I'll share it here just in case someone else is running non root & experienced this.

I figured it out.

  File "/home/chia/Swar-Chia-Plot-Manager/venv/lib/python3.8/site-packages/psutil/_pslinux.py", line 1992, in **nice_set**
    return cext_posix.setpriority(self.pid, value)

It was the process_priority setting in config.yaml:

**unix_process_priority: -15**

Changed it too

**unix_process_priority: 0**
