Hi guys, I'm very noob with jellyfin and need help with a very strange error. After some time running, my server start to go slow and finally stop to playback. Looks like something related to this error:
I also notice that my server "download speed" go to near 1mbps when this happens (the average speed is 90mbps ) . After stop/restart the jellyfin container everthing return to normal.
I'm running jellyfin using docker on umbrelOS (installed from umbrel app store). The host machine is a dual core with 8gbram and 1tb storage (367gb free).
Docker compose file:
