title: Sitecore package install never ends
body: <p>I got an interesting problem. When I install a Sitecore package the user interface never gets updated when the package is fully installed. The Sitecore package installation is hanging.</p>
  
  <p>In the Sitecore logs I see:</p>
  
  <pre><code>ManagedPoolThread #18 11:36:00 INFO  Installing item: items/master/sitecore/system/Tasks/Schedules/Portals/Default/{BEA47CD0-C3B3-4EFD-A781-997292620312}/nl/1/xml

  </code></pre>
  
  <p>This indicates that everything is installed correctly but in Sitecore the loading bar is still running.
  Does anybody know what can cause this because the logs are empty.</p>
