I have 2 instances of tomcat running on two application servers with same webtop and da deployed on both .I am getting this below error in one of the servers .I am also running the application on same port on the 2 servers.The application hangs after some time and unable to connect :-

SEVERE: The web application [/da] appears to have started a thread named [Thread-15] but has failed to stop it. This is very likely to create a memory leak.

Look for threads about the UCF hanging, especially regarding IPV6 handling.... There are a lot of them in the forums.
