Subject re: trying to make sense of thread dump in Tomcat 5.5.9

We are using Tomcat 5.5.9, and am having a problem with a memory leak.
Most of the threads in the thread dump have the similar stack trace as
this one does.

It doesn't make sense, because it seems that the ldap connection came
from the tomcat server, not from a web application.

We don't have any authentication set up to go to the ldap from the
Tomcat container, I do all my authenticating explicitly, through my web
applications.

How can I track down what is the cause of threads blocking going to the
ldap?

Thank you for any help.
