    Server Communication Lost - Multiple Sessions Per User?

      Recently upgraded to QV 10 SR4 (server and desktop software), and have noticed that there appear to be multiple sessions per user when trying to access some of the objects in our QVW deployed to the Access Point.


      For example:


      1. I begin to monitor the Status -> QVS Statistics -> Active Users portion of the Enterprise Management Console.

      2. I login to the QV server via my web browser remotely - I now show as having 1 active session.

      3. I can fully navigate around the server successfully, without any issue, until I go to open a SPECIFIC object.

      4. While that object attempts to load data, I see that I increment in sessions (now showing 2) in the EMC, under Active Users

           (NOTE: Only this SINGLE object instigates this behavior, and it does NOT happen when the object is opened in the Desktop app from what I've seen)

      5. After a timeout period (around 60 seconds or so) I get the 'Server Communication Lost..." and the file closes.



      So... I believe the problem to be CAUSED by the QlikView server opening up a separate, unique 'session' (yet, using the same browser on the client side) while loading the data in this particular object.


      I've tried adjusting timeout settings (after searching for others with similar errors), to no avail.  I'm also noticing the error logs specifying that the session was intentionally disconnected because it thought there were duplicate sessions opening up through the same user CAL (there aren't - except when the server 'thinks' that they are whenever this object is opened up).


      Any suggestions?  Parsing the data is near to impossible, so I'm looking for feedback as to what (if anything) can help me isolate what is causing this.
