PMS crashing when transcoding for specific Xbox One client

I’ve been having a reoccurring issue lately where PMS becomes unavailable, and needs the “Plex Media Server.exe” process killed and started again. In my case I believe I’ve narrowed my issue down to a specific Xbox One user.

When he begins watching something in a transcoded quality (example 720p 2mbps) and skips forward, I see 6 to 10 “Plex Transcoder.exe” processes start and max out the CPU to 100%. This continues for several minutes until the CPU goes back to idle utilization and at which point PMS is unresponsive. All processes, including all of the “Plex Transcoder.exe” remain idle. Killing “Plex Media Server.exe” and starting it again brings PMS back.

PMS version: 1.13.9.5456
Xbox One Plex App version: 2.21.1.70

I managed to download the logs when it was using 100% CPU prior to it crashing, and an additional set of logs once restarted from the crash.

Beta release 1.14.0.5468 has a fix for a deadlock that was triggered repeated seeks - seen a lot on XBox One

Please update and let me know if it fixes your issue. We already have confirmation from other users that the deadlock / freeze is fixed
