Who’s up for a challenge? Here’s my problem. Pretty much every time when I watch a show, at some point the video will stop completely. If I am watching in a browser, it will then drop back to the plex screen where I hit “Play”. If I was chromecasting, it will drop back to the plex logo. Sometimes there’s a generic error message about not being able to play the content, and sometimes there’s no message at all. So, everything seems to be set up correctly because I can play videos, but I keep getting these random stoppages. It does not seem to be related to the media in that it will not stop at the same point in the video if I play it again. Rather, I am pretty sure it is related to networking somehow…
When I look in the plex logs, there’s always an error logged at the same time as the crash. Typically it starts with this:

And then a few seconds later

And then again

So, I was thinking it might be related to networking. So I set up a script to ping google, my gateway (192.168.1.1) and localhost every 15 seconds from the plex server. Sure enough, when the crash happens, I can’t ping google or the gateway. Localhost is still successful. I also have a script running on a separate computer that pings the gateway every 15 seconds and that has no problems even when the crash happens. So I don’t think it is anything wrong with the router. So it has to be something in the server. I think. On the other hand, for the hours and hours in between movies, not a single dropped ping. The networking only stops when Plex is running.
By the way, this is a 14.04 Ubuntu server, and all of the updates are installed. The CPU is an Intel i3 3220 (passmark = 4200) and 8gb RAM.
OK, ninjas, what’s next? Everything was working great until maybe a few weeks ago. Watching shows like crazy with no problems at all. But now all of a sudden, I can’t complete a single show without a crash.
