[LoadUIWeb] Connection 9 of the scenario assigned to the virtual user "Virtual user group (278)" was simulated partially.

I'm experiencing the same problem while trying to verify my scenario. The only error I get is the "...simluated partially..." error. All the requests up to that point have an "Ok" status. There are no warnings to examine. I don't feel like I have enough information to throw over the wall to the developers, especially since I can run the same steps from within a browser without any errors.
