I do have the same problem that it increases until OOM.
For the time being I added a systemd timer to restart the docker container every 30minutes, so it doesn't hog all the memory and hangs the server (since the server also hosts DNS and other services inside the network).
On investigation it seems like it starts a jellyfin thread every other second[1]
inside the docker logs there is nothing from the time it says it started until the OOM[2]
No trickplay enable on any library and the following plugins enabled[3]
With enabled debug logs it looks like it does try to check the Scheduled Tasks all the time it increases the PID count[4]. Maybe the threads aren't closed after the check which contributed to the memory leak.
Happy to give you need more information if needed.
