Pebble's Stray Thread Killer
A server-side mod intended to fix server hanging on restarts by sending shutdown signal to hanging threads after main server thread shuts down.
⬇ Download on ModrinthIs your server console hanging when you issue a stop command? You're not alone. This mod is designed to solve that issue by managing non-daemon threads that often fail to shut down gracefully, causing the server to hang.
How It Works:
The Stray Thread Killer mod monitors the server thread during shutdown and detects any straggling threads that could prevent a clean stop. Once the server stop process is triggered, the mod waits for these stray threads for up to 5 seconds before forcefully sending a halt signal. This approach ensures a smoother shutdown process, allowing your console to reboot normally and preventing those frustrating hangs.
Features:
- Detects non-daemon threads during server shutdown.
- Provides a 5-second (configurable) grace period for these threads to complete.
- Sends a halt signal to ensure the server stops cleanly.
Note: This mod is intended to be lightweight and focused solely on addressing server shutdown issues.
