You're shutting node2 down gracefully? How are you doing it? Your symptoms sound more like a hard kill, where it's taking 15 secs for the other node to recognize missed heartbeats and suspect the dead node. To fix that you can add the FD_SOCK protocol to the JGroups config in the tc5-cluster-service.xml file. See http://wiki.jboss.org/wiki/FDVersusFD_SOCK for details.
