Filip,
Perhaps you can explain why each of these log messages are happening
every 10 minutes? If this isn't controlled behavior, which I doubt,
then something is going on here. =P
Thanks for the help,
Andy

correct, on the multicast IP

Is the multicast heartbeat picked up over the multicast IP or the
Receiver address that is broadcasted? I assume it is the multicast IP
as the Receiver is supposedly used for replication only.

the disappeared message appears 3seconds after the member added
message.
3 seconds is the timeout you have set, ie, if no multicast heartbeat
is
received after 3 seconds, consider the member dead.
so it seems like multicasting is not working properly on your system.

Good morning everyone,
I have been trying to get Tomcat clustering between two Tomcat
instances
set up, but I have run into some issues. After opening the necessary
ports in the firewall, routing the broadcast messages to the correct
network interface (eth0), and setting up server.xml with the
necessary
membership information, I get the following from my Tomcat logs:
2007-07-03 09:16:37,247 INFO

What could be the cause of cluster members disappearing immediately
after being added? Am I missing anything necessary for setting up
clustering / session replication? Relative information about the
server
is below.
Thank you,
Andrew
