Troubleshooting high CPU usage on idle

Server Version#: 1.15.5.994
Player Version#: n/a

Hello, I’m having an issue where the “Plex Media Server” process constantly runs full CPU load on one core.

I have tried disabling uPnP on my router to no effect. I have removed all the old plugins I had sitting around.
I’m not quite sure what to look for in the logs to help me figure out what is going on so any assistance would be most appreciated.
It’s only one core, so it’s not rendering my system unusable or anything, but I do not have a super powerful machine so when I do need transcoding to take place it often becomes an issue.

The UPnP bug in PMS requires that you restart PMS after disabling UPnP to get your CPU utilisation back down again.

Thanks for the quick response, that seemed to do it.

Do you know if this bug on the radar to be fixed anytime soon?

It’s received extensive investigation and diagnosis work from the community and we’re assured it’s on the internal bug tracker but have heard nothing beyond that other than an intention to wait for a new version of the cppnetlib software. I semi-regularly post in (After switching to Plex Pass PMS is constantly utilizing one core (version 1.14.1.5488)) as to whether or not it’s fixed in new releases when I get the opportunity.

Thanks again, I will subscribe to that thread.
Incidentally I am running OpenWRT as well…
