Cannot create cluster with JGroups Gossip router ------------------------------------------------ Key: WFLY-10046 URL: https://issues.jboss.org/browse/WFLY-10046 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 12.0.0.Final Reporter: Miroslav Novak Assignee: Paul Ferraro Attachments: standalone-full-ha-gosship1.xml, standalone-full-ha-gosship2.xml I've used config from EAP 7.1.0/WF11 where gossip router was configured in udp stack like: {code} <stack name="udp"> <transport type="UDP" shared="false" socket-binding="jgroups-udp"/> <protocol type="PING"/> <protocol type="MERGE3"/> <protocol type="FD_SOCK"/> <protocol type="FD_ALL"/> <protocol type="VERIFY_SUSPECT"/> <protocol type="pbcast.NAKACK2"/> <protocol type="UNICAST3"/> <protocol type="pbcast.STABLE"/> <protocol type="pbcast.GMS"/> <protocol type="UFC"/> <protocol type="MFC"/> <protocol type="FRAG2"/> <protocol type="TUNNEL"> <property name="gossip_router_hosts"> 0.0.0.0[12001] </property> </protocol> </stack> {code} Gossip router was started on localhost: {{java -cp $JBOSS_HOME//bin/client/jboss-client.jar org.jgroups.stack.GossipRouter -port 12001 -bindaddress 0.0.0.0}} but cluster does not form up. The same configuration works in EAP 7.1. Attaching xml config files for both of the servers.
