Jellyfin server filling up the RAM after a few weeks

[Polaris]

Hey everyone !

-Description of the issue
Even when left idle, after two or three weeks, Jellyfin server starts using all the RAM it can find on my machine (4GB out of 8GB).

-Version of Jellyfin
10.8.10

-Installation method and platform
Debian repository

-What client(s) you are using and how the issue manifests
I connect with the official Jellyfin apps for Windows and Android. I also use the website version sometimes.

-Any other context you might think is relevant

Other than filling up the RAM, everything works fine. My server gets somewhat slower, but it still makes room if I need something else.

The RAM gets cleared if I restart the Jellyfin service. A computer repairman and system administrator that I know said that all I need to do then is set-up a cronjob to restart it, but this solution feels like a band-aid, and I just want to be sure. Have I overlooked something ? Do I have a "proper" solution, so to speak ?

Thanks in advance ^_^

Apps, in general, will use as much RAM as the OS allows them to. A lot of the time, the consumed memory is for caching. And this is true for Jellyfin as well.

My server, after a fresh reboot, is using about 800MB of RAM. Memory usage over days and weeks usually creeps up to ~2.5GB, pretty much all of that increase is Jellyfin. I don't notice any slow down, but I'm only running JF and samba so it isn't doing a lot.

Your system shouldn't feel slower just from 50% memory usage, though. When you look at top are there any processes using a lot of CPU time? What about iotop? Anything using the disk when you notice these slow downs?

What are your full server specs?
