title: Application is shutting down. Reason: Configuration changed - any reason
body: <p>I'm encountering an app domain recycle, once in a a couple of weeks on my live environment. I've added healthMonitoring configuration to the web.config in order to get the reason for the application restart. When this recycling happened I got
  "<strong>Application is shutting down. Reason: Configuration changed</strong>" - event id 50004</p>
  
  <p>I've checked the files under the root path and non of them was changed - at least according to the modified date property.
  Also non of the machines.config nor the applicationHost.config were changed.</p>
  
  <p>Any idea how can I tackle this and understand what exactly cause this configuration changed event?
  Maybe which file was changed or which process caused the configuration change...</p>
  
  <p>Notice that I've checked that my application isn't changing any file on run-time.
  Also I've checked with my IT guy and it seems that no backup or Anti-Virus is running on this root.</p>
  
  <p>Any idea? </p>
