A ThreadAbortException is thrown when a call is made to the Abort method 
(documentation: 
http://msdn.microsoft.com/en-us/library/system.threading.thread.abort.aspx) 
on a thread. This is often called by the  *Response.End*, *Response.Redirect
*, or *Server.Transfer *methods, does your code use any of these methods? 
Here's some workarounds for those methods :

Here's some Stack Overflow questions that deal with the 
ThreadAbortException. Looking at these can help you diagnose some simliar 
trouble spots in your own code:
