there have been this kind of unfair competition with this guy going around crashing all the server so his own server can stay on top.
i think he do some kind of packet attack.
at first we encounter some weird bug like item switching all over the place.
like lapis icon on helm. armor.
wrong itemcount all over the place too.
and then after sometimes the ps_game crash.
here is the log.
i applied the enchant bug fix but sadly this is not the case.
mine was a ep4.5 ps_game.

(1c74.ad4): Unknown exception - code 00000000 (!!! second chance !!!)
i trimmed only the lines causing issue.
can anyone please help me to address this exploit?
well after checking the other threads i found another server facing the same issue as me.
i guess this kind of attack must be very popular these day.
pls point me in the right direction.
It seems like you got packet injection cause to crash. There are 2 options I can recommend:
1. Server side: Edit your ps_game.exe to drop the invalid merge item packets.
2. Client side: Attach an anti-cheat to your game.exe to prevent injection from running.
The #2 just a "buy-time" solution, if the "mental-guy" who did it to your server can bypass your anti-cheat system, then it will be crashed again, so it is better to have the fix on the server side. Of course, if you can deliver these 2 options, it will be more secure.
In additional, there was SQL Deadlock you need to check too.

hi there,
thank you for pointing that out for me.
unfortunately, i'm not familiar much with assembly and packet editing.
the server need to be up and running asap.
i'm willing to pay for the fix if you can do it.
in the meanwhile, i'll learn reverse engineering to better secure my server.
Yeah I know, I know you need the server is back up as soon as possible.
However, my advice is if you can not completely kill this exploit, do not re-open it, it will destroy your reputation in gamer's eyes, that is exactly the purpose of the "psycho-guy". Or you can think about upgrading your EP to 5.4 or above.
that's what i thought too.
upgrading was not an option since our home country "official shaiya" was dead at 5.3, so we stuck with the latest client which support our language (utf-8) at 5.3.
guess i'll stuck w 5.3 and waiting for someone who can fix this
