Have you verified with HTTPWatch or LiveHTTPHeaders that no 500's are returning? Maybe just some element of the the page is returning a 500?

 

 

Plus with that rule, a 500 won't trigger the failure variable to be set, only a 501 or higher. And once $failure is set to 1, it never gets set back, so every subsequent LB_SELECTED event will trigger the detach and reselect (so it will loop). You probably need to set $failure back to 0 once you're in the detach/reselect logic.
