Version information

mc1.19.3-0.4.6+build.20

Expected Behavior

Stable memory usage

Actual Behavior

I have -Xmx set to 8GB, my total RAM is 32 GB. Game starts with about 2.5 GB loading in my base. Entering Nether bumps it up by an additional 1.5 GB and moving around gives you about 2 extra GB for every 1km. Entities in the area also seem to increase RAM usage so just waiting around with mobs spawning/despawning will eat it up. Garbage collection seems to be completely absent. Depending on what I'm doing I get through my 32 GBs in about 1 hour. Game doesn't crash.

Mods

Sodium was the last mod I removed when looking for the source of the leak. I also tried vanilla 1.19.3 and fabric without any mods. The culprit is definitely Sodium.

I see there's been a commit 679e31b will test

Build https://github.com/CaffeineMC/sodium-fabric/actions/runs/3735810616 is fine, I'll stick with that until the next release.

The same happens to me on Windows 10, after some time uses all my 16 GB of RAM and then fills the pagefile until my storage is full and the game crashes. I'll try the build you provided.

Edit: The provided build fixes it for me too
