Overview

Crash Utilities is an essential toolkit for Minecraft server administrators, specifically designed to handle common maintenance tasks and emergency troubleshooting. The mod provides a suite of commands to retrieve logs, identify lag-inducing chunks, manage ground items, and assist players who are stuck or offline.

Unlike content-heavy mods, Crash Utilities focuses entirely on backend management and performance optimization. It does not add new blocks, items, or mobs to the game world, ensuring it remains lightweight while providing powerful diagnostic capabilities. It is particularly useful for modded servers where entity counts or tile entity complexities can lead to performance degradation.

Frequently asked questions

How do I open the Crash Utilities GUI?
Press CTRL + U on your keyboard to open the Crash Utilities interface. This is a client-side feature, so you can use it in single-player or on servers where the mod is installed.
Can I see what's causing server lag?
Yes—use the chunk map view to see loaded chunks and their entity/TileEntity counts, or use the entity buildup detection to find areas with excessive mobs or block entities. The RAM usage monitor also helps you track memory consumption over time.
How do I find and remove problem TileEntities?
Use the TileEntity locator command to search for specific block entities in the world, then remove or manage them directly through the mod's interface. This is useful for tracking down lag-causing machines or broken mod blocks.
Can I access another player's inventory?
Yes, the mod includes a command to open and read player inventories for moderation and troubleshooting purposes. It also supports Curio items, so you can see equipment stored in Curio slots.
