Let's hear a bit more about how you're using it. In particular, are you 
using any non-default QoS policies?

The comment in the IDL snippet indicates that "id_" is the key field, is 
that right?  Are you registering and/or disposing any instances?  How 
many instances are alive?  (My guess is that OpenDDS is intentionally 
keeping that memory to manage the various instances).
