Memory Leak Fix is a lightweight optimization mod that targets stubborn RAM issues in modded Minecraft. By patching several known memory leaks on both client and server, it helps your Minecraft server stay stable during very long play sessions, especially with large modpacks. Instead of performance slowly degrading, memory use remains far more consistent.
The mod focuses on fixing vanilla related leaks such as UI, particles, and resource handling, and is compatible with multiple versions up to Minecraft 1.20. It works on client side and server side, making it ideal for public or private Minecraft server setups we host at BoxToPlay.
