JGroups drops unicast messages after shutdown/restart (dropping unicast message to wrong destination) ----------------------------------------------------------------------------------------------------- Key: WFLY-2632 URL: https://issues.jboss.org/browse/WFLY-2632 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 8.0.0.Beta1 Reporter: Richard Achmatowicz Assignee: Richard Achmatowicz Fix For: 9.0.0.Beta1 JGroups drops unicast messages (citing wrong destination) after a node in a cluster is shutdown and then restarted. The JGroups version in use is 3.4.1.Final. Steps to reproduce: - start two nodes A, B using the server configuration standalone-ha.xml to create a cluster - shutdown A - restart A - after restart, we see these messages: {noformat} 13:15:03,227 INFO [stdout] (ServerService Thread Pool -- 63) 13:15:03,228 INFO [stdout] (ServerService Thread Pool -- 63) ------------------------------------------------------------------- 13:15:03,228 INFO [stdout] (ServerService Thread Pool -- 63) GMS: address=lenovo/web, cluster=web, physical address=127.0.0.1:55200 13:15:03,229 INFO [stdout] (ServerService Thread Pool -- 63) ------------------------------------------------------------------- 13:15:03,414 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (ServerService Thread Pool -- 63) ISPN000094: Received new cluster view: [fred/ web|3] (2) [fred/web, lenovo/web] 13:15:03,422 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (ServerService Thread Pool -- 63) ISPN000079: Cache local address is lenovo/web , physical addresses are [127.0.0.1:55200] 13:15:03,427 INFO [org.infinispan.factories.GlobalComponentRegistry] (ServerService Thread Pool -- 63) ISPN000128: Infinispan version: Infinispan 'Infinium' 6 .0.0.CR1 13:15:03,533 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: lenovo/web: dropping unicast message to wrong destination ac84f3e5 -f005-ddb2-b377-46b165e2aa77 13:15:03,609 INFO [org.infinispan.jmx.CacheJmxRegistration] (ServerService Thread Pool -- 61) ISPN000031: MBeans were successfully registered to the platform MBean server. 13:15:03,610 INFO [org.infinispan.jmx.CacheJmxRegistration] (ServerService Thread Pool -- 62) ISPN000031: MBeans were successfully registered to the platform MBean server. 13:15:03,765 INFO [org.jboss.as.clustering.infinispan] (ServerService Thread Pool -- 62) JBAS010281: Started default-host/distributable cache from web contain er 13:15:03,768 INFO [org.jboss.as.clustering.infinispan] (ServerService Thread Pool -- 61) JBAS010281: Started dist cache from web container 13:15:03,906 INFO [org.wildfly.extension.undertow] (MSC service thread 1-1) JBAS017534: Register web context: /distributable 13:15:03,978 INFO [org.jboss.as.server] (Controller Boot Thread) JBAS018559: Deployed "distributable.war" (runtime-name : "distributable.war") 13:15:04,033 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: lenovo/web: dropping unicast message to wrong destination ac84f3e5 -f005-ddb2-b377-46b165e2aa77 13:15:04,059 INFO [org.jboss.as] (Controller Boot Thread) JBAS015961: Http management interface listening on http://127.0.0.1:9990/management 13:15:04,060 INFO [org.jboss.as] (Controller Boot Thread) JBAS015951: Admin console listening on http://127.0.0.1:9990 13:15:04,060 INFO [org.jboss.as] (Controller Boot Thread) JBAS015874: WildFly 8.0.0.Beta2-SNAPSHOT "WildFly" started in 5193ms - Started 293 of 410 services (178 services are lazy, passive or on-demand) 13:15:04,533 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: lenovo/web: dropping unicast message to wrong destination ac84f3e5-f005-ddb2-b377-46b165e2aa77 13:15:05,034 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: lenovo/web: dropping unicast message to wrong destination ac84f3e5-f005-ddb2-b377-46b165e2aa77 13:15:05,534 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: lenovo/web: dropping unicast message to wrong destination ac84f3e5-f005-ddb2-b377-46b165e2aa77 {noformat}
