I've had Plex running on a Raspberry Pi 3 for a few months without issues and noticed that there was a update available - and of course, now that I've updated it, I'm having issues :'( Not sure what version I came from, but it would have been whatever was latest around the beginning of January, and it now has 22.214.171.12485. Raspbian was updated at the same time, (i.e. I did "sudo apt-get update" & "sudo apt-get upgrade" to update the whole system) and it was previously recent as of the beginning of Jan as well.
The behavior I'm seeing is that regardless of the client (have tried from both Xbox One and via browsers in a couple of different computers), browsing through the movies is fine and any movie I pick plays well for about 2-3 minutes or so. After that time though, the client indicates that's it's buffering but it never comes back from that state. If I quit the movie and try to browse around, all I get are wait indicators. The client is mostly unresponsive, movies are not shown. In a browser I see the chrome around the main area, but no movies or tv shows will show up, and even clicking on settings from the top bar will just end up resulting in a timeout. This happens until I reboot the raspberry pi, then all is good again until I try to play a movie. This happens regardless of the movie I'm playing - HD, SD, different bitrates, etc.
Looking at the syslog on the pi and the "Plex Media Server.log" file, it looks like one of the key processes involved is crashing shortly after sending enough data to the client to play back about 2-3 minutes of the movie.
Are there any known issues like this, or any ideas of what I can do to debug into it further?
