SmartRestart: Auto Server Restart for Minecraft Memory Issues
Server administrators managing complex modpacks know the frustration of sudden OutOfMemoryError crashes. Even robust hosting environments struggle when heavy resource packs and numerous plugins consume available RAM, leading to lag spikes and eventual server failure. The SmartRestart: Auto Server Restart for Minecraft Memory Issues utility provides an essential safety net by monitoring system resources and executing safe restarts before a critical collapse occurs. This tool is indispensable for maintaining high availability on public servers where manual intervention is not always immediate.
Automated Memory Monitoring Logic
Unlike basic watchdog scripts, this plugin employs a sophisticated algorithm to track free memory at configurable intervals. It continuously compares current available RAM against a user-defined critical threshold. Once the free memory drops below this limit, the system initiates a graceful shutdown sequence. Players receive advance warnings, the world state is saved securely, and the server reboots automatically. This process ensures data integrity while eliminating downtime caused by unexpected crashes. It is particularly effective for heavily modded instances running on Forge or Fabric loaders across supported versions like 1.16 through 1.20.
Customizable Configuration Parameters
The core strength of this utility lies in its flexible config.yml file, allowing precise tuning for any hardware setup. Key parameters include:
- check-mem-time: Defines the interval in seconds between memory checks. While the default is five seconds, administrators on lower-end hardware can increase this value to reduce overhead.
- free-mem: Sets the minimum free memory threshold in megabytes that triggers a restart. Small vanilla servers may function well with 100 MB, whereas large modpacks often require 200 to 300 MB to operate smoothly.
- Notification Messages: Fully customizable texts for initial warnings, countdown alerts, and post-restart notifications. These support color codes and multiple languages, ensuring communication remains consistent with your server's theme.
Installation and Command Overview
Learning how to install this plugin is straightforward. Simply place the jar file into your server's plugins folder and restart once to generate the configuration file. After adjusting the settings to match your allocated RAM, the system is ready. Management is handled via the smartrestart.sr permission node, granting access to vital commands:
/sr: Displays current free memory, the set threshold, and the check interval directly in the chat for quick diagnostics./sr reload: Applies configuration changes instantly without requiring a full server reboot./sr restart: Forces an immediate restart cycle, useful for manually clearing memory leaks during maintenance.
Essential Startup Scripts
To function correctly, the server must run within an infinite loop script that relaunches the Java process upon exit. For Windows users, a batch file utilizing a :restart label and goto command ensures the cycle continues. Linux and macOS environments utilize shell scripts with while loops and sleep commands to manage the restart cadence safely. These scripts allow you to specify exact Java arguments, such as -Xmx and -Xms, ensuring the plugin operates within your defined resource limits.
