Dupes that contain thousands of tiny, high-polygon entities that overwhelm the server's networking budget.
Periodically run server commands to clear disconnected players' props and loose constraints that degrade physics performance over time.
Lower your server tickrate from 66 to 33 if you run a heavy sandbox or DarkRP server. This gives the CPU more time to process heavy dupe spawns. gmod server crasher dupe free

Crashers typically exploit the way GMod handles entity spawning and data synchronization. Steam Workshop::Crash Dupe
The physics method is crude and easily detectable by anti-cheat addons (like ACF or simple prop limits). The malformed data method is more sophisticated but has been largely mitigated by updates to AdvDupe2 and OpenAI protections. This gives the CPU more time to process heavy dupe spawns
