LoadUI Agents constantly dropping packets

I agree. SoapUI seems to be very solid and LoadUI in local mode works pretty reliably as well. The agents, however, do seem to be very flaky--at least in current release. We have 6 test machines, each running an agent. The agents mysteriously come and go as they please. They often seem to be fine until the testing begins, and then they don't run any tests (I know this because they don't report any results to the Table Log. We even see them behave differently depending on who is logged into the test PCs.
