No More Zombie Threads
Ensures proper server shutdown by terminating lingering threads that prevent closure after /stop
Screenshots
About this Mod
Did you ever had your server refuse to shut down after running /stop? Annoying, right? That’s because some mod developers forgets to close async threads, preventing the server from shutting down properly.
NMZT fixes this by forcefully terminating any lingering "zombie" threads after the world and playerdata have been safely saved. No more manually killing your server process after every restart or crash — NMZT handles it for you.
✅ Features:
- Fully automatic. You can literally just put the mod in your mods folder and completely forget about this problem.
- Lightweight. This mod implements only 2 hooks into the vanilla code and nothing else, so it will NOT reduce the server performance.
- Safe. NMZT is 99.9% compatible with other mods, so I don't think it can break your world or modpack.
You can add this mod to any modpacks w/o asking me.
