Error: SusbcriberNotFound - "...no eligible subscribers to receive the message... "

NeuronESB v3.5.4.1100

I have a Publisher that publishes (send) to a topic. I have a Subscriber that subscribes (receive) from that same topic.  The subscriber has nothing except the topics (receive) and the business process (on receive).  The Business Process is thoroughly tested and solid.

Attached to the Subscriber is a Business Process that

1. gets the message
2. makes a C# http client RESTful call
3. receives an XML response
4. sends the xml to a stored procedure for inserting data into a database

It works fine when:

1. I use the TEST Clients to test the entire Pub/Sub it works fine.
2. I use the adapter to receive the message and publish it and use a single TEST client to receive the message

It FAILS when

• I do not use any test clients. 
• This is a business process that consumes the message and nothing else. 
• The Subscriber with a Business Process is supposed to complete the entire process.

How do I get this to work without using the Test Client?

The Goal is to receive a message and run a Process inside of Neuron.

I have tried variations of a final step in the business process to be a

• CANCEL -- failed
• TRACE -- failed
• <nothing> -- failed

It only fails when there is not a TEST Client connected to the Subscriber.

Here is the error message:
