Having an issue with ajax calls.... I think..?

Hey guys,

I have a website called keychat.com, where people go to create chat sessions, which the can return to at anytime and share with anyone.

I am using jquery to run the site, and the problem the site is having is that when you are in a chat session, the ajax calls fail at random times (at lest I think that is what the issue is).

here is a screen shot of what firebug says when it crashes:



I have searched up and down the internet trying all sorts of things and I have not been able to resolve the issue. Could someone please look over the javascript source code see if they see anything that is; incorrectly done or not efficiently done which would cause the problem.

I would also greatly appropriate any advice on how to make the code more efficient too.
