Can you provide the netstat (because of having a look at other 
connection stati aprt from ESTABLISHED).

Unfortunately the thread dumps show that Tomcat is basically idle. Three 
threads are connected to the redirector and wait for the next request, 
and one thread actually works on a request (ag_005fclassifschemes JSP).

A few additional threads are sitting idle in the pool, waiting for 
handling future connections.

The picture is the same in all 3 dumps.
