NPC dies, and nobody can login any more / account already logged in bug

I'm using RuneSource, and there's a specific dog at Brimhaven dungeon that crashes the server after it dies and the loot appears. The weird thing is, I can kill other dogs (npc 1593) and the server doesn't crash, just the one that spawns at (2676, 9556) causes this issue. I can literally kill the dog 5 squares away with no issues. I've been trying to debug the issue and i noticed that the player instance is being reconstructed right after the crash occurs, and then the disconnect method is logged to the console right after. The logout method is never called. There are no exceptions being printed to the console. The server remains online,but no one can connect.

Why does this affect ALL players? Instead of only affecting the player whose instance is being restarted for some reason. What part of the server would be responsible for this behavior?

edit: I also want to note that this is a consistent behavior. I can restart the server 100 times and get the same result.

I would disable instances and see if the issue still occur. If it does, I would debug all the instances and see which one create at where and have a look at which one is being mean to the server.
You're best bet is to keep an eye out till you found the issue and fix it.

OT:
What happens if you remove the npc spawn - does it happen when killing any of the other dogs instead?

This sounds like you are having issues with some kind of recursive call

(If there are any methods or loops in your loot method make sure there is a logical condition in which these loops terminate or your program will hang here trying to do whatever it's supposed to (The reason why all players DC because the server stops sending packets because it's occupied elsewhere probably stuck in a infinite loop))

Common causes would be while loops or methods which call their selves and have not been properly set to escape.

DIsable which instances? I don't think you mean player instances because that would probably break a lot of things lol.

No, only the dog that spawns at that those particular coordinates will cause the issue. I have time to quickly pick up the loot, and then the player will freeze and the client will send me to the login screen, even though the logout method has not been called on the server side. Other dogs of the same id, I can kill all day .



I get the feeling that this is intended to be some super difficult to debug antileech or something..

Well if it is only about those dogs, perhaps you should have a look at any detail / code about / with the dogs and try locate something.

bump m8

I originally thought this could have been caused by my SQL integration saving and loading, but I've ruled out that possibility by reproducing the bug on an original version of the source that scu11 posted way back:

This has got to be an anti-leech... I just want someone to tell me where to look and what part of the server is blocking/nullifying connections after this happens.
