How to crash a server?

Hey everyone,

I know what i ask is a bit.. evil .. but i wonder how to crash a COD4 server /
Im not gonna crash every cracked serv i play on lol don't worry, i'm just curious.

I know the game uses a modified q3 engine.
In JK:Jedi academy which use also Q3 engine, you just had to exec something with a very long message to crash the server ^^. Havn't tryed yet but i don't think it works in COD4.

anyone help?.

If u defuse the bomb and press /quit the server will go offline.
