Even paused transcode tasks, the 'Plex transcoder' process still in high cpu usage

Server Version#: Version 4.123.2
Player Version#: -
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>


This is expected behavior.

it is the reason why there is a setting called “Terminate Sessions Paused for Longer Than”
https://support.plex.tv/articles/200430283-network/

Educate your users to utilize the Stop :black_square_button: button.

Why do we need so many resources to maintain a paused task?
Or, maybe, Is there a schduled transcoding function? That can also solve my problem.

No Stop button found for transcode tasks

I mean the Stop button in the player.

Thank you for your reply again

But all I mentioned were transcoding tasks

What do you mean by “transcoding task”?


Sorry, my fault. I mean Optimize tasks. Transcode high quality movies to lower quality for the mobile devices.

Ahh, understood.

Actually I’m not sure why this would still cause the CPU load to remain that high.
When I Pause an optimization job on my server, CPU load is reduced to almost zero after a few seconds.
(But that is not on a NAS device, so might not be comparable.)

For Plex transcoder process, there will indeed be times of decline; But after a while, there will be high CPU usage again

Are you certain that this transcoder process is indeed the paused optimization?

I have paused my test optimization again, for 15 minutes and I don’t see the CPU load creeping up again.

Yes, sure

Looking at my previous reply, I put two browser pages together and took a screenshot of it

paused_transcode

record the screen for it

pause the optimize task, the cpu usage do goes lower, but still in high percentage.

May I see the server DEBUG log files ZIP please?

Plex Media Server.log (2.7 MB)

Unfortunately, debug level logging has been disabled. Valuable information is missing from the log files.

  1. Please re-enable debug, not verbose, level logs.
    Settings → Server_Name → General + Show Advanced

  2. Restart Plex Media Server.

  3. When the problem re-occurs, download a new set of log files.
    Settings → Troubleshooting.

  4. Upload the entire ZIP file to the thread.

Could you please confirm if this log is correct?
