This guide assumes that the node can join the cluster, but can't join a service.  If the node cannot join a cluster, ensure that multicast is functioning correctly via the Multicast test or that WKA (Well Known Addresses) is correctly configured.

When a Coherence node joins a cluster, it must receive confirmation from every node in the cluster for every service that it is configured to run.  If a new node does not receive confirmation for a service, it will not be able to join it.  Therefore, the goal is to identify the node(s) with the unresponsive service thread and remove it from the cluster by shutting down its JVM.
