Hi Narasimhan
     From what i understand from this post is that the application data is not getting downloaded to the client from the server and the data is in O-waiting in the middleware.  One possibile reason for this is because of time out in the ABAP Sync Service.  There is a parameter named <i><b>icm/keep_alive_timeout</b></i>  which indicates the time between the last successful query and the termination of connection.  The default value for his parameter is 60 seconds.  Increasing this value to a higher value (preferably in minutes, depending on your landscape and amount of data) will definitely help. You can probably set the value of this parameter to around 10 mins.
   Go to transaction RZ11 and enter the above parameter name to display the current setting. Inorder to change the default value, please refer to note 824554 which describes this in detail
Hope this helps
Best Regards
