Hi Filip,

I think I am seeing the message, it was just hidden amongst other log messages 
I guess I missed it.

However I do see something else when I added the TcpFailureDetector to the 
interceptor list, I see two DISAPPEARED messages?

Without TcpFailureDetector:

        1) Start Server #1, then #2
        2) Unplug #2 network
        3) On #1 - #2 DISAPPEARED, on #2 - #1 DISAPPEARED
        4) Reconnect #2 to network, on #1 - #2 SHUTDOWN;#2 ADDED, on #2 - #1 
ADDED

Add TcpFailureDetector

        1) Start Server #1, #2
        2) Unplug #2 network
        3) On #1 - #2 DISAPPEARED;#2 DISAPPEARED, on #2 - #1 DISAPPEARED;#1 
DISAPPEARED
        4) Reconnect #2 to network, on #1 - #2 SHUTDOWN;#2 ADDED, on #2 - #1 
ADDED

I take it I get the 2 DISAPPEARED messages because I have another interceptor, 
but is this the correct behaviour?

TIA
Mike

there are getters and setters for everything
and they are all documented here
http://tomcat.apache.org/tomcat-6.0-doc/config/cluster-channel.html

each component has getters/setters, for example, the multicast address

setAddress
getAddress

breakpoints might not work very well, since you are stopping one thread, 
and not really emulating a real scenario.

again, sounds like you have a simple test case, if you can share that, I 
can get more understanding, and help you further.
