Master node enters tight loop calling getClusterCoordinatorState on remote node ------------------------------------------------------------------------------- Key: MODCLUSTER-47 URL: https://issues.jboss.org/browse/MODCLUSTER-47 Project: mod_cluster Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 1.0.0.Beta3 Reporter: Brian Stansberry Assignee: Paul Ferraro Priority: Critical Fix For: 1.0.0.Beta4 Attachments: node1-modha.log, node2-modha.log To reproduce: 1) Install the mod_cluster 1.0.0.Beta3 sar on two nodes. 2) Configure a value for the proxyList config (don't know if this is relevant, just the way my setup is) 3) Add a war that's not excluded to both nodes 4) Start node1 5) Start node2 After node2 starts, node1's background thread goes into a loop calling getCoordinatorState on the other node, repeating as soon as a response is received: 2009-02-03 16:36:08,120 DEBUG [org.jboss.modcluster.ha.HAModClusterService] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Check status for engine [jboss.web] 2009-02-03 16:36:08,122 TRACE [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) callMethodOnCluster(true), objName=HAModClusterService, methodName=getClusterCoordinatorState, members=[192.168.1.146:58895] 2009-02-03 16:36:08,125 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) dests=[192.168.1.146:58895], method_call=HAModClusterService.getClusterCoordinatorState([MCMPServerStateImpl{address=/127.0.0.1,port=6666,state=OK,establishedtrue}]), mode=2, timeout=60000 2009-02-03 16:36:08,126 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) real_dests=[192.168.1.146:58895] 2009-02-03 16:36:08,184 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) responses: [sender=192.168.1.146:58895, retval=org.jboss.modcluster.ha.rpc.ModClusterServiceStateGroupRpcResponse@37bb7c19, received=true, suspected=false] 2009-02-03 16:36:08,187 TRACE [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) callMethodOnCluster(true), objName=HAModClusterService, methodName=getClusterCoordinatorState, members=[192.168.1.146:58895] 2009-02-03 16:36:08,187 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) dests=[192.168.1.146:58895], method_call=HAModClusterService.getClusterCoordinatorState([MCMPServerStateImpl{address=/127.0.0.1,port=6666,state=OK,establishedtrue}]), mode=2, timeout=60000 2009-02-03 16:36:08,187 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) real_dests=[192.168.1.146:58895] 2009-02-03 16:36:08,199 TRACE [org.jboss.ha.framework.server.ClusterPartition$RpcHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) responses: [sender=192.168.1.146:58895, retval=org.jboss.modcluster.ha.rpc.ModClusterServiceStateGroupRpcResponse@1d64d42f, received=true, suspected=false] 2009-02-03 16:36:08,199 TRACE [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) callMethodOnCluster(true), objName=HAModClusterService, methodName=getClusterCoordinatorState, members=[192.168.1.146:58895] and so on
