SOLVED: Music library got borked somehow

[Ginjutsu]

Hi y'all. I just started running into some issues with my Jellyfin library recently. To provide a little background, I've been running Jellyfin via Docker using the official image since mid 2019. I've never had any issues like this - it's always worked very well, even when I had upwards of 20,000 songs added. However, just recently, I noticed that when adding new albums, the metadata doesn't get automatically picked up - the album will show, and the track list will appear with the raw file names displayed, but that's about it. I need to manually go to the album page and hit the "Scan for new and updated files" button for the rest of the data to show up properly - that includes the actual track titles, album art, album artist, etc. While not a big deal, this can get pretty annoying when I'm adding something like, 20 albums at one time. I need to search up each album name, find it, rescan, etc. You get the picture. This started happening suddenly a few weeks ago after a scan failed (not sure why), and it hasn't worked right since.

That brings us to today - I tried adding another album (it was a pretty big one, coming in at around 100 tracks), and after I went into the album page to scan it, it fails to load (just an endless loading wheel any time I try to view the album). Not only that, but the section for "Newly Added Music" on my homepage now no longer appears. When using Feishin to play songs from my library off my computer, the "Home" page just loads endlessly, and I suspect it has something to do with the odd state my server seems to be in. I'm only able to find albums and songs via the search function in both Feishin and Jellyfin Web. In addition to this, the album, artist, and song pages in Jellyfin Web also load endlessly. I've completely removed the 100 song album and rescanned, but no luck - things are still broken.

Does anyone have any idea what could be happening here? I wanted to post a log snippet, but when it's at 50,000 lines, I'm not sure where to even start when looking for the relevant info. If anyone could point me in the right direction here, I would very much appreciate it

I should add that I'm currently running the most recent version of Jellyfin, 10.10.6.

Can you share your jellyfin logs via privatebin.net? Also, what distro is running the docker container? And can you share your docker compose as well?

Sure thing, I've uploaded it here: https://privatebin.net/?2ad311b532a90e4d...he431XKRSt

It's quite large, so fair warning. I have a trimmed down version here which contains what I believe to be a relevant error snippet: https://privatebin.net/?e057cc066121591d...vHKQkk73rL

I'm running through Synology's Docker application and used Portainer to set up Jellyfin, so I'm not sure if there's a way I could extract a Docker Compose file from that since it's not a Stack. Any time Jellyfin pushes an update I just recreate from latest and am usually good to go. Is there anything that you'd like to see in particular regarding the setup, or should I just screengrab the portainer page?

Set this docker environment variable to 0.

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT

Set this docker environment variable to 0.

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT

I don't know what that did, but it worked! My music library is functional again and metadata is being grabbed automatically. Thank you so much!

Now I'm curious how this happened in the first place

[TheDreadPirate]

That variable controls how DOTNET handles non-english characters. When set to one, it pretty much breaks Jellyfin's scanner if you have media with non-English characters.

I don't know why or how, but some systems will have this set to 1 and some 0. By default containers will inherit the system default. Unless you specify it with that docker environment variable.
