Strange logs during in memory replication

[Rafal Zawadzki]

Hi. I set up clustering with in memory session replication. The fragment of my 
config is (tomcat 5.5.12):

        <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="228.0.0.5"
                mcastPort="45564"
                mcastFrequency="500"
                mcastDropTime="3000"/>

            <Receiver
                
className="org.apache.catalina.cluster.tcp.ReplicationListener"
                tcpListenAddress="auto"
                tcpListenPort="4002"
                tcpSelectorTimeout="0"
                tcpThreadCount="60"/>

            <Sender
                
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
                replicationMode="pooled" ackTimeout="15000"/>

            <Valve 
className="org.apache.catalina.cluster.tcp.ReplicationValve"
                   
filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/>

At http://tomcat.apache.org/tomcat-5.5-doc/changelog.html I read, that in 
5.5.13 there were many bugfixes connected with clustering. But it is stable? 
When 5.5.14 will be stable? Ok, the strange logs are:

Thanks for help
