PlayBackInfo hangs forever...

[dopeshow 0]

Hello,

 

I'm test driving Emby, however I'm facing and odd issue... sometimes (randomly, no specific trigger) Live TV stops working at all. When I try to watch Live TV using my web browser, the spinning circle lasts forever. Opening developer tools, I can see that a request to PlayBackInfo is marked as "pending" and never completes. I can try a different stream and get the same results, the only solution that works is to restart emby.

 

Here are some specs that might help:

 

Stream origin: .ts file

OS: Linux

Emby Premiere: Enabled

Remuxing enabled, transcoding disabled (however transcoding isn't needed as once emby is restarted, live tv works again).

 

server log: http://54.39.128.64/emby.txt (last 1000 lines, as it was a huge file > 200 Mb)

 

Thanks in advance.

@@dopeshow, hi, this is really strange. what kind of live tv is this? what kind of tuner?

 

And this only happens on live tv?

@@Luke yes, it only happens on live tv... VOD seems to keep playing just fine. So far we've tried with .ts and .m3u8 streams.

 

By the way, I've confirmed that the .ts and .m3u8 streams work flawlessly as they are on the same LAN and I've had them running on VLC at the same time as the error presents itself.

Can you enable debug logging under logs, then restart the server, repeat the test, and attach the complete emby server log? thanks !

@@Luke I think I've been able to find the main issue... At some point I find this:

From what I can see (I'm not a big SQLite fan) it tries to access a table/database that is marked as locked by the same server (no, I'm not running 2 instances). A while ago I quit using SQLite because it had issues with systems that need to read/write lots of data. The media library in this server is kinda big (about 40k items), and it has 10 concurrent users... maybe that's the problem?

Can you try rebooting your system? I know you're saying you're not running two instances, but that's pretty much always the cause of this. Thanks.

There's only 1 instance... will follow your suggestions and reboot later, even though the "reboot fixes all" is usually a Windows concept, as I manage servers under Linux and BSD that have been up for over 3 years without a single reboot...

 

I've also monitored processes, CPU usage, RAM usage, disk I/O and all of them are at "normal" levels.
