[Cloud9Developer]

How large is your library?

[derrezzz]

More than 20k files

[devpatf]

getting the same error randomly with about 30k items (episodes + movies).

using latest 10.9.2

[Xameon42]

I am unsure whether the first and second errors are related, as I have only noticed the second error in my installation so far.
I have also tried to reproduce this and in my case the error can be triggered by playing an episode from a very large series (>1000 episodes).
Smaller series (tested with one with just over 600 episodes) do not trigger the error for me.

Same issue on Docker but only since 10.9.5:

Can't scan any new media into Jellyfin now. Is the only solution to wipe everything and start again?

[TheNamelessWonderer]

Ran docker compose down and then docker compose up -d and this has fixed the issue. When I updated I only did docker compose pull and then docker compose up -d. This shouldn't really make a difference but it is working now.

Edit: issue is back now. After using Jellyfin for a bit longer.

[VerityIncorporated]

Hi,

I am going through the same problems.

This is intermittent and affects watch history, progress, etc. but they happen predominantly to library.db SQLite database as I stated earlier.

But the jellyfin.db is being used properly by the Docker container and it reads/writes to config/cache folders without any problem. I would also like to mention that my configuration and cache directories are on the host machine rather than inside of the Docker container in my set up. These two locations are mounted at /config and /cache respectively. Moreover, all other data including reading and writing does not have any issues in this respect.

Please update to 10.9.6

[EcceGratum]

Had 100% repro while scanning a music folder, 10.9.6 fixed it for me.
