I have constantly high CPU usage (50-80%) After I’ve updated PMS on my QNAP 253A to version 1.20.1.3252. Even without anything playing. I’ve already optimized databases. I just saw there’s even newer version so I will try to update to that one and see if it helps.
Do you share your server with others and allow them to Sync?
I checked user activity on server and nobody else had been active in a long time and while CPU usage was high which I believe it was for at least a whole day before I started troubleshooting.
After I upgraded Plex package for qnap the CPU-usage went down. Maybe a restart would have fixed the issue as well if it was some kind of intermittent issue.
