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.
About this Mod
Is 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.
