Library no longer auto updating post upgrade

[Moots]

I'm running Jellyfin along with the arr applications in containers on a Synology NAS. It's all been working fine until yesterday when I updated the container image for Jellyfin/Sab/Sonarr and Radarr to the latest versions available, Jellyfin is version 10.10.7 if that helps.

Since the update when any media is downloaded it doesn't automatically update and appear in Jellyfin, I can manually scan the libraries and it works fine but it's not being picked up based on changes anymore.

I've had a look in the logs and can't see any obvious error in relation to trying to refresh the data, and it doesn't seem like a permissions issue given that it worked previously and a manual scan works without any issues.

Any advice would be greatly appreciated.

Spotted this error in the logs

Implementations.IO.LibraryMonitor: Error in Directory watcher for: "/Tv/Tv"
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.

I had to increase the Max user watches from 8192 using SSH, and then set up a scheduled task to ensure it doesn't go back to the default after a reboot. Now appears to be working.
