Review request for geode, Hitesh Khamesra and Udo Kohlmeyer. Repository: geode Description ------- When a member crashes or there is a network partition the new GMS was performing many final-checks in GMSHealthMonitor for the same member(s). This overloaded the system quite a bit, causing a large jump in the number of health monitor threads. JGroupMessenger was also using checkIfAvailable() instead of suspect() when there were IOExceptions thrown in JGroups messaging, which exacerbated the problem if the network were actually down.
