Commands

Crash

crash [client|server] [game|jvm]

  • client - Make a crash to client. This argument only works on client-side.
    • game - Make the game crash. This argument is the same as pressing F3 C for 10 seconds on a client. Default option.
    • jvm - Make the JVM crash. This argument is the same as pressing Ctrl F3 C for 10 seconds on a client.
    • If no argument is specified, default is game.
  • server - Make a crash to server. This argument only works on server-side.
    • Sub-arguments are the same as client
  • If no argument is specified, it will be executed depending on environment.
    • When executed on client with this mod (regardless server host or player), the result will be like crash client.
    • When executed on server console, or by server player without the mod (when has proper permission), the result will be like crash server.

Known Issues

  • If you join the server as player, and you have permission level 4, the client argument is not suggested and the server argument is not executed. This is not a Crash Command bug. Learn more

Notes

  • The mod file name indicates the mod name, loader and version:
    • (mod name)-(mod loader)-(mod version)-mc(built minecraft version).jar
    • For example: Fabroxy-fabric-1.0.0-mc1.19.3.jar
  • youJustLostTheGame method is used in this mod. Unfortunately, since I'm using Yarn mapping, the method is written makeJvmCrash not youJustLostTheGame in source. If you want to know funny topic about this method, please watch the PhoenixSC's video. Learn more

Frequently Asked Questions

Crash Command server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.8). You can switch loaders with one click in the panel.

Is Crash Command compatible with fabric?

Crash Command officially supports fabric for Minecraft 1.21.8, 1.21.7, 1.21.6. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Crash Command – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Crash Command consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
