Hi there, we're running two different jboss clusters in the same network(currently just one node per cluster). Problem: Annoying UDP-Warnings in server.log: | 16:42:32,291 WARN [UDP] discarded message from different group (Tomcat-<PartiotionName>). Sender was <hostname> | I've set different partitionnames via the jboss.partition.name property(just calling "-Djboss.partition.name=..." at startup). I've changed the UDP mcast_addr and the mcast:port in the cluster-service.xml as seen below to different values and i've set the property: discard_incompatibe_packets="true" But those log messages are still bugging me! :O servernode1: | <Config> | <UDP mcast_addr="${jboss.partition.udpGroup:228.1.2.4}" mcast_port="45567" | ip_ttl="${jgroups.mcast.ip_ttl:8}" ip_mcast="false" | mcast_recv_buf_size="2000000" mcast_send_buf_size="640000" | ucast_recv_buf_size="2000000" ucast_send_buf_size="640000" | loopback="false" discard_incompatibe_packets="true"/> | servernode2: | <Config> | <UDP mcast_addr="${jboss.partition.udpGroup:228.1.2.3}" mcast_port="45566" | ip_ttl="${jgroups.mcast.ip_ttl:8}" ip_mcast="false" | mcast_recv_buf_size="2000000" mcast_send_buf_size="640000" | ucast_recv_buf_size="2000000" ucast_send_buf_size="640000" | loopback="false" discard_incompatibe_packets="true"/> | What is going wrong here?
