Jellyfin server filling up the RAM after a few weeks

[TheDreadPirate]

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?
