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?
