Auto Restarter

Auto Restarter is a small NeoForge mod for Minecraft 1.21.1 dedicated servers. It automatically restarts the server, sends warnings to players, and can also restart the server when TPS gets too low.

Description

🔄 Auto Restart & TPS Guard

A powerful, lightweight utility designed for dedicated servers to maintain peak performance. This mod ensures your server stays fresh by scheduling restarts and protecting against heavy lag spikes.

✔ Key Features

  • Scheduled Restarts: Set automatic restarts every X minutes to prevent memory leaks and long-term lag.

  • Smart TPS Monitoring: Automatically triggers a restart if the TPS (Ticks Per Second) drops below your defined threshold for too long.

  • Fully Customizable Announcements: Notify players before a restart occurs. You choose the timing and the exact messages.

  • Advanced Configuration: Every single aspect is now highly tweakable via config/auto_restart.properties.

  • Clean Shutdowns: The mod safely saves the world and kicks players before stopping to ensure zero data loss.

  • In-Game Commands: * /restart — Manually trigger the restart sequence (OP only).

    • /timeuntilrestart — Let players check how much time is left before the next scheduled reboot.

✔ How it Works

  1. Detection: The mod identifies a restart is needed (either via schedule or low TPS).

  2. Notification: It sends your custom warnings to all online players.

  3. Shutdown: The mod stops the server cleanly.

  4. Looping: Your run.bat or start.sh script detects the stop and immediately launches the server again.

✔ Example Restart Script (run.bat)

To use this mod, your startup script must be set to loop. Here is a perfect example:

 

Code-Snippet
 
@echo off
:loop
java -Xms10G -Xmx10G (your flags here) @libraries/net/neoforged/neoforge/21.1.199/win_args.txt %*

echo Server stopped. Restarting in 10 seconds...
timeout 10 >nul
goto loop

 

Note: Always run the server using this .bat/ .sh file, not by double-clicking the JAR directly.

✔ Configuration

The new version features an extremely flexible configuration system. You can find everything you need in: config/auto_restart.properties

You can customize:

  • Exact intervals for scheduled restarts.

  • Minimum TPS threshold and duration (how long TPS must stay low before reacting).

  • Multiple announcement intervals (e.g., 10m, 5m, 1m, 10s warnings).

  • All localized chat messages and colors.
