connection refused, simple the Tomcat instance is unable to open a
connection to the other instance to send the replication data.
your systems will continue to function, but if you fail over that other
node might not have your data.
You'll want to find out why it is failing to open a connection, maybe
the other node is broadcasting the wrong address,
you should see the address and ports in the log as the members join the
cluster, and you can take it from there.

Hi all,
In a tomcat cluster deployed in production, I'm seeing the following
in catalina.out:

I'm getting these at quite an alarming pace at the moment. AFAIK,
service is not affected since we ourselves are albe to use the
application satisfactorily, and have not had reports of wide-spread
failures.
This is on Redhat AS3 linux machines with tomcat 5.5.17 with java
1.5.0_06. Following is my cluster configuration (abbreviated):
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
expireSessionsOnShutdown="false"
useDirtyFlag="true"
notifyListenersOnReplication="true">
<Membership
className="org.apache.catalina.cluster.mcast.McastService"
mcastAddr="228.0.0.4"
mcastPort="45564"
mcastFrequency="1000"
mcastDropTime="30000"/>
<Receiver
className="org.apache.catalina.cluster.tcp.ReplicationListener"
tcpListenAddress="auto"
tcpListenPort="4001"
tcpSelectorTimeout="100"
tcpThreadCount="6"
compress="false"/>
<Sender
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
replicationMode="fastasyncqueue"
compress="false"
doProcessingStats="true"
queueTimeWait="true"
waitForAck="false"
autoConnect="false"
keepAliveTimeout="360000"
keepAliveMaxRequestCount="-1"/>
[..cut for brevity..]
What should I be looking at changing? Any ideas?
Thanks in advance,
