OOM Errors related to Jellyfin - RoyalFaceMelter - 2025-02-09

I have posted about this here before and I THOUGHT the issue was resolved, but no appearantly not. I am not even sure if it's Jellyfin related, but the UnRAID system logs always mention Jellyfin so I wanted to create a new thread on it.

So I put all of my logs from the 05:00 hour this morning on Pastebin:
https://pastebin.com/bXNB8rZk
-- I suggest cntrl+f Jellyfin, it's a ton of logs.


Here's my Jellyfin docker run:

Can you check if this environment variable is set?

Code:
MALLOC_TRIM_THRESHOLD_=131072

On the command line you'd use this command to see all of a container's environment variables.

Code:
docker exec -it jellyfin env

I don't see the MALLOC_TRIM,

Here is the output of the command you provided:

Set the environment variable "MALLOC_TRIM_THRESHOLD_" (including the underscore at the end) with a value of 131072.

Hey, one question:

I haven't set the MALLOC_TRIM_THRESHOLD_ variable yet. This morning I did upgrade my RAM in my server to 64GB (rather than 16GB)...do you think/or recommend that the MALLOC_TRIM_THRESHOLD_ variable should still be necessary? I guess I am not sure what it does, that's why I am asking.

RE: OOM Errors related to Jellyfin - TheDreadPirate - 2025-02-13

It should always be added. Jellyfin can still use a lot of memory with or without that env variable (usually from ffmpeg), but the env variable will help ensure it doesn't grow out of control unnecessarily. It's configures Jellyfin/DOTNET's memory management functions.

Alright, I got that env. variable set. Hopefully with the RAM upgrade and that variable, I'll finally be in the clear. Thank you so much for your help on this, and thanks for taking the time to explain what the change did.
