No backend server available for connection: timed out after 10 seconds

 Basically have a forms server setup with Weblogic 11g. Forms and Reports servers are setup and have started fine with no error messages. These forms are pulling information from an oracle db.

Go to the webpage and form comes up where it asks to generate reports. I choose a county that has a small data and i choose to submit, it generates the report fine as required. But if I choose an option with a huge amount of data and i hit submit I get the following error:

No backend server available for connection: timed out after 10 seconds or idempotent set to OFF
