Jellyfin closes/stops on NAS ever 12 hours or so instead of staying up

[stapler]

Hi guys, 

I have Jellyfin installed on my Synology NAS server. It's going well, but it randomly crashes maybe once or twice a day while I'm not using it.
I would like Jellyfin to always be live/running, otherwise I can't access it anytime, anywhere, and have to log into my NAS and manually start the application again. I've also shared access to Jellyfin with some family members located in different households; if it's not always running, they have to message me to start it up again sometimes. 

Is there any way for me to either ensure it never closes, or to get it to auto-restart when it does crash/close?

• The version of Jellyfin you are running (e.g. 10.8.10)
  

10.8.13-13

• Your installation method and platform (e.g. Linux Docker, Debian repository, Windows installer, etc.)
  

Package Center on Synology NAS 1019+ (Linux)

• What client(s) you are using and how the issue manifests
  

Since Jellyfin has closed on my server, it won't open on anything until I go in and manually start it again.

• Any other context you might think is relevant
  

I used the Jellyfin on the official Package Center instead of installing via Container Manger/Portainer. Maybe that's the issue? 
The logs of Jellyfin don't seem to indicate why it crashed/closed its self.
