Diagnosing "Thread was being aborted." in ASP.NET - asp.net

Question

I am receiving a "Thread was being aborted." in the stack trace of my ASP.NET application. I am attempting to use the WinDbg technique described here to diagnose:
http://blogs.msdn.com/b/asiatech/archive/2012/06/21/how-to-troubleshoot-httpexception-request-timed-out-asp-net-4-0-64-bit.aspx
Right now I am just trying to catch this in the sample asp.net application provided. I can get the asp.net application to timeout but I can't get the dump described in the article to generate. I think I need help from a WinDbg person to understand where I am going wrong. I am including the WinDbg entries. My output is a bit different but I can't tell which address to use in the aspnet_timeout.cfg file described.

Answer 1

This log shows that you have a TimeOut somewhere. But you must have some other event on your computer that shows in witch page you got that time out.
If you have many times out you first need to locate the page that cause that, maybe a download page that hold the session, or a page that need more time to runs than the Timeout set.
This execution timeout is set on web.config with 110 seconds default value:
<system.web>
<httpRuntime executionTimeout="110"/>
</system.web>
