+Summary: Intermittent crash when ASPX downloads other pages
+
+Description of Problem:
+One web page has code that loads up an XmlDocument from an HTTP source. 
+Mono intermittently crashes.  It seems to be after a period of inactivity
+(between 10-20 minutes)
+
+Steps to reproduce the problem:
+1. I'm afraid I don't have a simplified case to reproduce the problem.  I'm
+hoping that the included stack trace below is all you need.  If a
+simplified case is required, I may be able to provide it.  Just add to this
+bug.
+2. 
+3. 
+
+Actual Results:
+
+Server error in '/' application
+Description: Error processing request.
+
+Error Message: HTTP 500.
+
+Stack Trace:
+
+System.ArgumentNullException: Argument cannot be null.
+Parameter name: asyncResult
+in <0x00045> System.Net.HttpWebRequest:EndGetResponse (System.IAsyncResult)
+in <0x00066> System.Net.HttpWebRequest:GetResponse ()

+in <0x002e8> ExecuteHandlerState:Execute ()
+in <0x00084> StateMachine:ExecuteState
+(System.Web.HttpApplication/IStateHandler,bool&)
+
+
+
+Expected Results:
+A loaded XML file --> a loaded web page
+
+How often does this happen? 
+After 10 minutes or so of inactivity.
+
+Additional Information:
+It looks like an asynchronous call to GetResponse in incorrectly
+terminating, based on the stack trace.
