Hi, it seems like your issue report has the following item(s) that need to be addressed:

• You have not filled in the environment completely.

This is an automated message, currently under testing. Please file an issue here if you encounter any problems.

[David-Moreira]

I've just updated to 10.9 and I also noticed jellyfin started crashing when playing a video sometime after, it could be 10m it could be 30m really couldn't tell exactly, so I also can't tell what might trigger it. By checking the logs I've seen a similar error with content mismatch. Since I personally don't have alot of time to troubleshoot I reverted back to a backup in v10.8.13

But I'd like if we can keep an eye on this and figuring out what triggers this behaviour.

[VampiricAlien]

@David-Moreira I have skip intro scanning and I belive this is causing thh ATV client to crash randomly. I've asked Niels about this and he says "The app crashed because your server is not responding," the app being Android TV app. Before the update this never happened. I did notice the API endpoint was updated that plugins use, maybe https://github.com/jumoog/intro-skipper is slowing down jellyfin. I have checked the server and it's fine. Jellyfin seems overloaded?

[David-Moreira]

I see. I can confirm that I am also using the same intro-skipper plugin.

"The app crashed because your server is not responding,"

Edit: Yes that's the behaviour I had. Whatever jellyfin client is playing stops playing (but does not crash), and the server becomes completely unresponsive until restarted.

[VampiricAlien]

Everything was fine until I told it to scan but is the issue jellyfin or the plugin and is this issue anything to do with the server becoming completely unresponsive?

[gnattu]

If you are having issues with scanning causing the server to hang, can you try reduce the scan concurrency to a conservative value like 1? It is located in the Dashboard -> General the performance section. The default concurrency value could be too high for your disk and causing all kinds of IO hang.

[jumoog]

Please try scanning without the plugin

[David-Moreira]

Oh in my case even though I do have the same plugin intro-skipper plugin it was not scanning, as I only scan on "off-hours".
I had this behaviour at least 3 times before going ahead and just reverting back to my backup since I don't have time to troubleshoot today.
So I wouldn't be so sure it's an issue with the scanning?

[jumoog]

Scanning works fine. I notice that it removes old TV series from the DB that no longer exist. But after scanning everything went fine. Overall very high IO.

[VampiricAlien]

@gnattu There was no number set,

Parallel library scan tasks limit is now 4
Parallel image encoding limit is now 2

@David-Moreira that to me says it might not be the plugin.

[jumoog]

Whats your ulimit?

[gnattu]

@gnattu There was no number set,

Parallel library scan tasks limit is now 4 Parallel image encoding limit is now 2

@David-Moreira that to me says it might not be the plugin.

No number set = 2* logical cpu count, a very high concurrency

[VampiricAlien]

@gnattu Would be a good idea in the text field to mention CPU count.

[David-Moreira]

@VampiricAlien are you able to reproduce the issue though? In order to properly test these settings you're changing?

[gnattu]

@gnattu Would be a good idea in the text field to mention CPU count.

We plan to reduce the concurrency to a more conservative number in the future because this default value is too high for most of the underlying disks.

[VampiricAlien]

@David-Moreira
I have set it to 2 and is playing fine atm , I will set it to 1 since 2 didn't work. Iit's Monday morning for me.

[VampiricAlien]

After setting it to 1, nothing was able to connect for about 10 minutes or so. I have removed the value.

[VampiricAlien]

https://github.com/jellyfin/jellyfin/releases/tag/v10.9.1 New update for 10.9. Will install this now.

@gnattu After 10.9.1 update Parallel library scan tasks limit was still set at 0, now set at 2
(Default to processor count concurrent scan instead of 2 * processor count)

[Raul824]

could anyone tell me how is the intro skipper working in jellyfin 10.9.
I tried uninstalling and reinstalling from the fork of Bobby306 but it always says Not Supported post installation.

You'll need to install https://github.com/jumoog/intro-skipper for it to work

[David-Moreira]

@VampiricAlien how's it been with 10.9.1?

[VampiricAlien]

@David-Moreira Same as 10.9.0

[David-Moreira]

@VampiricAlien have you tried 10.9.2?

[VampiricAlien]

@David-Moreira Yes, Fixed the crashing of the server and also fixes the websocks that causes skip into not to work.

[VampiricAlien]

Closing the issue, seems there was a problem with 10.9.1 update. No longer see this error in log with 10.9.2 update.
