Historically, this is often achieved using the addon or specific Prop-Spawn exploits. A "crasher dupe" specifically refers to a duplication contraption so complex or buggy that its mere existence or spawning forces the server software to crash. How Does a Crash Dupe Work?

The GMod developer community has created highly effective tools specifically engineered to detect and block malicious dupes before the server attempts to render them.

There is no single “crasher dupe.” Instead, there are several archetypes of attack. Each exploits a different weakness in GMod’s Source engine or its server addons.

In Garry’s Mod, the Duplicator tool allows players to save a collection of props, entities, and wires, and spawn them instantly. A "crasher dupe" is a corrupted or intentionally overloaded duplication file designed to exploit the Source Engine's limitations. gmod server crasher dupe

These duplicates can be anything from simple props to complex entities like NPCs or vehicles. Once created, the duplicates can be manipulated to move rapidly around the game world, causing the server to struggle to keep up with the increased load.

Interlocking props inside one another, forcing the physics engine (VPhysics) to calculate millions of impossible collisions per second. Historically, this is often achieved using the addon

Automatically detects physics lag freezes and deletes the offending props before the server dies.

Essential for blocking unauthorized toolgun usage and restricting who can spawn specific types of dupes.

These exploits are highly destructive and go beyond simple cheating: Constant crashing makes a server unusable.
