Hi List,
Below is my server.xml configuration for session replication.
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6"/>
<Manager className="org.apache.catalina.ha.session.BackupManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true" mapSendOptions="6"/>
<Channel
className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.McastService"
address="192.168.3.14"
port="45564"
frequency="500"
dropTime="30000"/>
<Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="5000"
selectorTimeout="5000"
timeout="60000"
maxThreads="6"/>
<Sender
className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport
className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"
timeout="60000" keepAliveCount="0"/>
</Sender>
<Interceptor
className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor

<Interceptor

</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/>
<ClusterListener
className="org.apache.catalina.ha.session.ClusterSessionListener"/>
We are continuously getting following logging in our catalina.out. Can any
one explain me why it is saying Operation has timed out(3000 ms.)
How do i resolve it. I have searched the archive mail & change the setting
according to it. However, no luck. Server is getting high load after adding
session replication for backup manager. Your valuable response will be
highly appreciated.
SEVERE: Unable to send message through cluster sender.
