Well, i had a JKJA Dedicated server once, but after it has been crashed over and over again, i turned id off... just a few moments ago i read the exploit description again and it came over me. this exploit is caused by the handling of chat messages. so the solution is so simple: just change the chat system to prevent the crashing.

~~~~~

edit the lib (base/jampgamei386.so in my case).

find any lines like:
say: %s: %s
sayteam: %s: %s
tell: %s to %s: %s

and overwrite the last %s with spaces (OVERWRITE, not delete, that's important!!!). The lines now should look like this:
say: %s:  
sayteam: %s:  
tell: %s to %s:  

~~~~

Now the exploit does not work anymore, but the chat messages will still displayed on the screen. have tested if others can see them too, they can...

Pro: server does not crash anymore
Contra: no say_team, no tell

Hope that helps.

P.s. Ravensoft, plz dont lawsuit me for messing with your binarys ^^ if this is agains any laws in your country or just against your company guidelines (or just you dont like this), please remove this post and never mind.

If you guys want, you can call this a "Patch" and release it as you had invented this solution, i dont claim any rights on this idea, i just want to help other ppl playing this awesome game you made

P.p.s. i reanimated my Server, you can find the IP/Port on my Page and test it for yourself.

MFG
