    JBoss cluster (UDP) error on AIX 64

    Scott Mutchler Newbie

      I'm trying to setup my first JBoss cluster on AIX (64 bit). I would like to setup the cluster to use unicast but I want to get it working with multicast first. I get the following error on startup:

      2007-03-08 16:03:09,854 DEBUG [org.jboss.deployment.MainDeployer] End deployment start on package: tc5-cluster.aop

      Here are configuration files:

          Try disabling IPv6 (described on the JGroups wiki)

            Thanks that was it. All I had to do was add:

            -Djava.net.preferIPv4Stack=true

            to the JBoss startup.sh.

              The cluster now startups up but I get the following error from the second node (every minute):

              10:57:38,550 ERROR [UDP] exception=java.io.EOFException

              and this message from the first node every minute
