Jellyfin freezing my pi4b

[CacheToWin]

I have recently changed from Plex to jellyfin because I didn't like it anymore.

Jellyfin really has been a blast but for some reason my pi sometimes completely freezes and I need to reboot it before it works again.

First idea was high temperature but I made a temp log script that looks completely fine (end of post).

I did notice when I would open jellyfin on phone. Close it and later (10-15min) watch on tv the pi would have alot of usage. When Running top I would have multiple jellyfin processes running. My guess is that for some reason a couple of apps keep running in the background and my pi just can't handle it and freezes. 

Any idea what I could do/test? Or how I can make sure the instance from tv etc is completely 'dead'.

Info:
Jellyfin running inside container on portainer (along side other containers).
Version: 10.10.4 
Jellyfin resources are already limited with portainer. Just added ram to it.

Can you share your jellyfin logs via privatebin.net?

Is Jellyfin running off of the SD card or an attached SSD?
