Cleanup collection task

[FrederikSchack]

Hi,

I got most things to work in Jellyfin and thanks to this forum I got collections to get cover art, but now the other collections that I managed manually were emptied. One was a collection of IPTV channels, the other was a collection of my top movies.

It could be the scheduled task CleanupCollectionAndPlaylistPathsTask that is cleaning out items that it can't find for some reason, I have several lines of this:
[08:19:38] [INF] [8] Emby.Server.Implementations.ScheduledTasks.Tasks.CleanupCollectionAndPlaylistPathsTask: Item in TV Channels cannot be found at null

Anybody with experience in this? And any suggestions how to handle this?

Can you share your full jellyfin log via pastebin?

Can you share your full jellyfin log via pastebin?

I'm going to paste for the relevant period where the folders were emptied. We had a power outage, so there was a server restart, which triggered the container cleaning and I suspect that this caused the emptying.

Is your collection for live TV channels?

You can disable this in Dashboard > Scheduled tasks. Open the playlist cleanup job and delete the trigger to run it on startup.

They are IPTV channels and favorite movies, they all got cleaned out. I guess I can live with not having the cleanup job running

I just noticed this part.

Code:

[08:19:34] [ERR] [8] Emby.Server.Implementations.IO.LibraryMonitor: Error in Directory watcher for: /data/tvshows
System.IO.IOException: The configured user limit (8192) on the number of inotify watches has been reached, or the operating system failed to allocate a required resource.

Are these network shares? Do you have real time monitoring enabled for these libraries? If yes to both, disable real time monitoring. NFS and SMB do not support that. NFS does, in theory. In practice it doesn't.

Oh, thanks a lot, I didn't know that. 

Yes, they are network shares, although on a virtual network.

My configuration:
Windows 2022 Server
-SMB Shares
-Hyper V
--Alpine Linux
---Docker
----Jellyfin

The SMB Shares are mounted as CIFS volumes in Docker

From my experience, this is the nicest setup for me. I don't like to nerd excessively
