HFM Applications Stop Responding and Display a Blank Screen.

Hello,

We are having an issue with our HFM applications that occur at random times within our environment.  We are an 11.1.2.2 305 EPM/HFM/FR/FDM environment, running on Windows 2008 with MS SQL 2008 R2.

What happens is the HFM applications stop responding and all your see within the browser is a blank screen.  Workspace and other components work fine but any access to our three HFM applications just display a blank screen.  It takes a restart of services to get the HFM applications to start responding again. 

This occurs roughly once every month.  I have an open SR but so far we haven’t found a solution.  We’re planning to restart services every month right before month end.
