[omniORB] Memory leaks

Hello
When I stop my application, running under windows 2000, the Microsoft Visual
C++ logs the following info debug (I have paste just some lines of it).
My code never pass trough "orb->destroy()". Could it be the cause of the
memory leaks?
Can I do something not to have these?
I have read other questions in this list about memory leaks, but I can't see
how to solve my problem.
Thanks
