The cluster-service.xml file doesn't control any TreeCache instance. Most likely the one you're seeing logging from is the cache used for HTTP session replication. That's configured in deploy/tc5-cluster.sar/META-INF/jboss-service.xml. Basically the same type of process of using a different cluster name, mcast_addr and mcast_port should be applied to that file as well. The ip_ttl change can be done there too.
