Hi Adrian, What is your program doing after it calls pn_message_send? That function queues the message for delivery but the delivery isn't actually transferred until the application yields the control back to the Proton reactor (via pn_proactor_wait). If the application is doing other processing or waiting on a condition or mutex, the delivery won't go out the door immediately.
