Chris:
You are right this is INFO message and not an ERROR.
We didn't find anything in the log that suggesting there is a
successful connection. What those successful connection message suppose to
be?
Thanks
Gary

Where does the server hang? On logins? Do you have a thread dump of a "hung"
server?

This often happens because a firewall terminates a long-lived connection. When
encountering an error like this, Tomcat should retry its connection and
work-around any such termination. You can see that this is an INFO message and
not an ERROR. Does Tomcat eventually log anything suggesting that there is a
successful connection?
