Hello,

Can someone try to explain what this Catalina.log snippet is saying in regards to \
clustering status?

It looks like to me, this machine successfully sent a session data state msg to the \
other machine in the cluster, but 60 sec later the other machine did not respond with \
with its session data state

Any ideas why clustering is not working?

Here is how I have clustering defined in server.xml
