Excessive RAM consumption

Okay, I'll do that.
I also tried deleting the Docker container and recreating it (while keeping my appdata, of course), but that didn't change anything.

For me, the solution would be to migrate to another repository like "lscr.io/linuxserver/jellyfin".
However, I would need guidance on the steps to follow because simply copying the appdata didn't work—the new linuxserver database didn't like it. 😆😜

Alternatively, I could wait for version 10.10.10 , which should introduce a backup feature, making the migration to another repository much easier.

Are you using the official image now?  If so, the linuxserver image uses a slightly different config directory layout to the point that the official and linuxserver images are not interchangeable.
