100% CPU, becomes unresponsive, no activity?

Plex Media Server
1

Server Version#: Version 1.40.1.8227

Hi All,

I have an extensive library. I have 24 core Xen CPU with 128G of RAM. Plex DB etc runs on SSDs.

Randomly, my server becomes unresponsive. I have to restart the docker container daily.

I can see the plex PID @ 100% CPU. Plex grinds to a halt.

I’m trying to figure out why. It wasn’t transcoding, and no one was streaming. It’s not scanning library files or generating previews/intros, etc. It is idle.

I enabled debug logs, but all I can see is 3-4 logs every few seconds of players checking in… nothing interesting.

Can anyone help me to t-shoot what Plex is doing when it goes to 100% CPU and becomes unresponsive?

Thanks!

Is it possible someone tried to start streaming a movie?

hmm could be. i can’t see any work around in that thread tho :frowning:

Can somewhat try to prevent it by force-refreshing metadata for the movie first a few times, but it’s not guaranteed.

Unfortunately once it happens it just keeps going forever until you quit the server.

Hmm, i reverted back to 1.40.0.7998-c29d4c0c8 and it no longer is causing issues.

Seems the latest update caused it for me

I hope that is true as its a sneaky problem since you can’t tell which movie is causing it from the logs. If you suspect a movie though you can use the “view xml” option under “get info” that will spike the cpu, you can repeat this to bring your server to its knees :wink:

refreshing the metadata on the movie often will fix it, but as you add new movies it can then happen on those

My issue might be unrelated as i saw the spike after a server restart and nothing had been played. Reverted the version and i no longer see the issue.
