Wes,
It seems that you are accumulating senders in the service process. You
create one per response but never close them. Try adding
"sender.close()" after the send in the service program.

I have been seeing some strange behavior with the 0.20 C++ broker (I see the
same behavior in the 0.14 broker as well) when sending / receiving messages
with the Python API. It seems that the response time increases for each
consecutive message.
The client sends a message with a reply-to field and waits for a response.
The service receives all messages and immediately replies to the reply-to
address.
I have attached my test code to the bottom of this email. Please let me know
if I am not cleaning something up properly or misusing a class.
Here is the result of running the client code 10 times in a row without cycling
the service.

Cycled the service.
And another result of running the same client code 10 more times.
