SEVERE: Unable to start cluster.

Hi List,

Below is the error we are facing while starting tomcats.

SEVERE: Unable to start cluster.
org.apache.catalina.tribes.ChannelException: java.net.SocketException: Not
a multicast address; No faulty members identified.


Our cluster setting is as below in server.xml


 <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6">
        <Manager className="org.apache.catalina.ha.session.BackupManager"

         <Valve

       <ClusterListener

     </Cluster>



Note: 192.168.3.14 is the IP of backup manager with java & 192.168.3.9 is
the IP address of local tomcat where above server.xml is hosted.

Please guide us as to how to overcome the issue & please give us the sample
<cluster>   </cluster>  file if possible.
