Comment 3 for bug 1525214

In looking at the test and the history, it seems that this test passes sometimes and sometimes it doesn't. I think we need to add an additional wait after all services have been stopped prior to starting the health checks.

I believe we are hitting the resources before the pools have completely cleared the controller that is no longer running.
