Can you design a very minimal program that proves your point ? Something that do loop over
a bind/unbind/close would help.

Alos provide the Java version you are using, the LDAP API version you are using and the server
you are connecting to (and its versin).

A useful information would also be a thread dump captured when your application is eating

Thanks for the report !
