Can you take a dump of your client application when it is in HUNG state using the Debug Diagnostic 2.0 tool ( http://www.microsoft.com/en-us/download/details.aspx?id=40336 ) and then analyze the file Dump by simply double-clicking the .dmp file and seeing a column of the stream freezing when trying to create a DataCacheFactory?
This will give an idea of ββwhere the thread is currently stuck and should help in figuring out the cause of the problem.
To collect a process dump, you can simply install the tool and open the tool, and then click "Cancel" in the "Rules Wizard" and go to the "Processes" tab, find your client process, and then select Create a full user Dump
