title: Server Hangup IIS
body: <p>We have had reports from some users today of getting the error "Server Hangup".
  They see a blank page with this error message at the top and underneath the message "Description: Server Hangup"</p>
  
  <p>They see this error when using an ASP.NET MVC application at a particular screen that is calling a WCF web service on another server. The application is hosted in IIS 7.5.</p>
  
  <p>Any ideas on how I can track down the source of this issue?</p>
