ChunkRescue
ChunkRescue is a server-side utility plugin designed for Folia and other multi-threaded Minecraft server environments. It helps reduce downtime caused by problematic chunks that may trigger severe lag, partial crashes, crash loops, or continuously low TPS.
What does it do?
When the server enters an abnormal state, ChunkRescue attempts to record the suspected problematic chunk coordinates and safely stop the server when necessary. On the next startup, before the affected chunk is normally loaded, the plugin backs up the original chunk data and removes the abnormal chunk so the server can regenerate it from the original world seed.
Features
- Detects suspected bad chunks during severe lag or crash-like situations.
- Records problematic chunk coordinates for recovery.
- Performs recovery during server startup before the chunk is fully loaded.
- Backs up the original chunk data before deletion.
- Allows the server to regenerate the affected chunk using the world seed.
- Helps prevent repeated crash loops caused by abnormal chunks.
Important Notes
ChunkRescue is designed as an automatic fallback mechanism, not a full replacement for manual crash investigation. It may not detect every possible crash source. Regular full-server backups are still strongly recommended, especially for production servers and public survival servers.
