You're changing the wrong port.
You should not change the mcastPort, instead you should change the tcpListenPort
The mcastPort and mcastAddr should be the same for every instance participating in the cluster.
Also, as a word of advice, it's best to keep the cluster size down to 2-3 ( and at most 4 ). we've had a lot of trouble with larger cluster sizes, not because of any fault of the cluster manager, just that it's a huge (network/memory ) resource hog having all your sessions replicated six times over. Of course, this is only for our case so YMMV.

Here is the cluster info that i have in my server.xml.
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" name="etrakCluster1" managerClassName="org.apache.catalina.cluster.session.DeltaManager" expireSessionsOnShutdown="false" useDirtyFlag="true">
<Membership className="org.apache.catalina.cluster.mcast.McastService"
mcastAddr="228.0.0.106"
mcastPort="45100"
mcastFrequency="500"
mcastDropTime="3000"/>
<Receiver className="org.apache.catalina.cluster.tcp.ReplicationListener"
tcpListenAddress="auto"
tcpListenPort="4001"
tcpSelectorTimeout="100"
tcpThreadCount="6"/>
<Sender className="org.apache.catalina.cluster.tcp.ReplicationTransmitter" replicationMode="pooled"/>
<Valve className="org.apache.catalina.cluster.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.htm;.*\.html;.*\.txt;"/> </Cluster>
my mcastAddr range is from 228.0.0.106 - 228.0.0.115
and the ports run from 45100-45109.
Note each host has its own cluster entry and i have 10 different hosts.
This is on tomcat 5.0.19 running on slackware 9.X
Would i need to reboot the server to clear this up?
Is this a problem with clustering or could it be a setup problem on my part.
Thanks,
Daniel Schulken
