How to crash a c3 server. : Lineage 2 Submissions

Well, I used this thing to crash my old server.First of all you need to have tradeable strider.So let's start:

Player1 has the strider.
Pleyer1 sits down and sells the strider.
Player2 clicks ok and a new window appears saying "are you sure you want to buy...." and you have 2 selcetions, Ok and Cancel. You leave this window as it is.
Player1 stands up and summon the strider.After he sits down and sells again the strider.
Player2 buys the strider.
Player1 mounts his strider and BOOOM! You just crashed the server
