[jboss-user] [Clustering/JBoss] - Upgrading jgroups

I am currently using jboss AS 4.0.3 in the all configuration and am trying to upgrade jgroups to version 2.4CR2 to take advantage of the TCP_NIO functionality, however when I startup the second node in my cluster I get the following exception: WARN [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] failed unserializ | ing message buffer (msg=[dst: <null>, src: 192.168.200.99:7801 (2 headers), size = 492 bytes]) | java.io.StreamCorruptedException: invalid stream header | at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:753) | at java.io.ObjectInputStream.<init>(ObjectInputStream.java:268) | at org.jboss.invocation.MarshalledValueInputStream.<init>(MarshalledValueInputStream.java:60) | at org.jboss.ha.framework.server.HAPartitionImpl.objectFromByteBuffer(HAPartitionImpl.java:135) | at org.jboss.ha.framework.server.HAPartitionImpl.handle(HAPartitionImpl.java:943) | at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:623) | at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:508) | at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:331) | at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:763) | at org.jgroups.JChannel.up(JChannel.java:1078) | at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:377) | at org.jgroups.stack.ProtocolStack.receiveUpEvent(ProtocolStack.java:393) | at org.jgroups.stack.Protocol.passUp(Protocol.java:538) | at org.jgroups.protocols.pbcast.STATE_TRANSFER.up(STATE_TRANSFER.java:163) | at org.jgroups.stack.UpHandler.run(Protocol.java:60) | If anyone can offer any help, it would be much appreciated View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981804#...
