Sridhar Iyer [http://community.jboss.org/people/sri4jb4rel] created the discussion "JBoss Clustering 5.1 (Discovery Interrupt Failure)" To view the discussion, visit: http://community.jboss.org/message/645886#645886 -------------------------------------------------------------- I am planning to do a set up of JBoss Clustering using the community version 5.1.0. Followed the instructions mentioned in the link http://docs.jboss.org/jbossclustering/cluster_guide/5.1/html-single/index... http://docs.jboss.org/jbossclustering/cluster_guide/5.1/html-single/index.... But post deploying the 2 node cluster once in single machine and second try I did in two machines. In both the cases I am getting the below error continuously post the server are started. I am able to view the applications in stanalong httpURLs but due to the below error i m confused to understand if really my instances are part of the cluster Moreover i never find in the logs of the server that my custoem cluster has two nodes participated My question remains 1) Has the cluster formed properly? 2) How to check if an instance is part of a customised cluster and its member nodes? Is there any way in JMX console 3) How to verify if Muticast is working properly or not? *Error in both server log is* ########################################################################################################################## 2012-01-11 11:52:25,370 ERROR [org.jgroups.protocols.MPING] (Timer-2,10.185.254.80:7901) failed sending discovery request java.io.InterruptedIOException: operation interrupted         at java.net.PlainDatagramSocketImpl.send(Native Method)         at java.net.DatagramSocket.send(DatagramSocket.java:625)         at org.jgroups.protocols.MPING.sendMcastDiscoveryRequest(MPING.java:341)         at org.jgroups.protocols.PING.sendGetMembersRequest(PING.java:259)         at org.jgroups.protocols.Discovery$PingSenderTask$1.run(Discovery.java:407)         at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:417)         at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:280)         at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:135)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:65)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:146)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:170)         at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:651)         at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:676)         at java.lang.Thread.run(Thread.java:637) ########################################################################################################################## *When verified what is port and IP combination i found its not related to my cluster.* Please check the GSM below its of Messaging ########################################################################################################################## --------------------------------------------------------- GMS: address is 10.185.254.80:7901 (cluster=MessagingPostOffice-DATA) --------------------------------------------------------- 2012-01-11 11:16:08,061 INFO  [org.jboss.jms.server.connectionfactory.ConnectionFactory] (main) Connector bisocket://10.185.254.80:4557 has le asing enabled, lease period 10000 milliseconds 2012-01-11 11:16:08,061 INFO  [org.jboss.jms.server.connectionfactory.ConnectionFactory] (main) org.jboss.jms.server.connectionfactory.Connect http://community.jboss.org/mailto:ionFactory@15d8350 ionFactory@15d8350 started 2012-01-11 11:16:08,072 INFO  [org.jboss.jms.server.connectionfactory.ConnectionFactory] (main) Connector bisocket://10.185.254.80:4557 has le asing enabled, lease period 10000 milliseconds ########################################################################################################################## *Wrt to my Cluster 'DEVCLUST' I dont find differnt nodes participating*.
