Monsters stop dropping items/meso & attacks not working properly

[QueenTitania]

I'm using MoopleDev v120 source for a v83 server.

The bug starts whenever it wants, anywhere between an hour and 18 hours after the server has been online. It begins with one person not getting any drops or mesos from monsters randomly... and then it seems to slowly spread over the whole server until nobody is getting drops from monsters. Characters also have trouble attacking the monsters, for example genesis would not kill a snail. Or avenger would only kill 1 mob instead of all 5 mobs it hits...

While I read this thread first: http://forum.ragezone.com/f566/monst...s-meso-937735/
No concrete fix was stated...
As far as I've been able to figure out, ConcurrentModificationException is the problem, however I do not know how to fix this.

Any help?

Well, this is actually a pretty easy fix. You probably try to adjust or change something in the MAPLECHARACTER.Java and messed the drops/looting ... I suggest you get a clean MapleCharacter.Java and replace it and then attempt to try.

It sounds more like a memory leak to me. I wasn't aware of MoopleDEV rev 120 having a serious memory leak like that, so maybe iiLick's solution would be the faster option (although it's funny that 3/4 of their posts say the same thing in different threads haha).

If a lot of your work is not portable to a clean copy of Moople, you'd have to profile the application to try and determine what the cause is. If you're using Netbeans as your IDE, you can read more about profiling in relation to your problem here https://netbeans.org/kb/articles/nb-...leaks_pt1.html
