Hello,

I am trying to upgrade my modcluster version from 1.1.x to 1.2.6. These are the steps we followed from a previous forum thread on this issue : Correct way to upgrade mod_cluster in JBoss AS/WildFly?

1. Replaced mod_advertise.so mod_manager.so mod_proxy_cluster.so mod_slotmem.so in /usr/lib/apache2/modules/ with new versions from mod_cluster-1.2.6.Final-linux2-x64-so.tar.gz

2. In jboss/modules/system/layers/base/org/jboss/as/modcluster/main, replaced:

     mod_cluster-core-1.2.3.Final.jar, mod_cluster-container-catalina-1.2.3.Final.jar, mod_cluster-container-jbossweb-1.2.3.Final.jar, mod_cluster-container-spi-1.2.3.Final.jar

    with 1.2.6 versions from mod_cluster-parent-1.2.6.Final-bin.tar.gz

3. Updated module.xml with the new file names

When we startup JBoss, we see this message:

23:58:55,113 ERROR [org.jboss.modcluster] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) MODCLUSTER000042: Error null sending INFO command to 192.168.11.1/192.168.11.1:6666, configuration will be reset: null

23:58:55,131 ERROR [org.jboss.modcluster] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) MODCLUSTER000042: Error null sending INFO command to 192.168.11.2/192.168.11.2:6666, configuration will be reset: null

The IP addresses of master and slave respectively are 192.168.11.1 and 11.2

Is there anything more that needs to be done to get this to work? I don't see these errors if I revert back to my old version of mod cluster. Any help is much appreciated
