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.
In the Sitecore logs I see:
ManagedPoolThread #18 11:36:00 INFO Installing item: items/master/sitecore/system/Tasks/Schedules/Portals/Default/{BEA47CD0-C3B3-4EFD-A781-997292620312}/nl/1/xml

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.
