Have you read Michi Henning and Steve Vinoski's book, "Advanced CORBA
Programming with C++"?  At least the sections about ServantLocators?  If
not, I strongly recommend that you do so.

It creates an object reference in the POA with the given id. That is all
it does.

It generates an object reference and returns it. It is your
responsibility to release the reference it gives you.

Do you release the object references given to you with
create_reference_with_id?  If not, that's the cause of your leak.  As an
aside, why are you calling create_reference_with_id inside preinvoke?
That's an unusual thing to do there.

Cheers,
