Service Bus AMQP force detach Qpid Proton C client

Hello,

I compiled Qpid Proton C library on Ubuntu and I can send and receive message to/from Service Bus using AMQP 1.0 protocol.

On the receive I have a problem...

After receiving the message, the library returns the following error :

LINK ERROR (amqp:link:detach-forced) The link 'receiver-xxx' is force detached by the broker due to errors occurred in consumer(link653)..TrackingId:bba7c767bc18406dba821e5ab4e698c0_G5_B14;12886:652:653,TimeStamp:4/15/2014 3:19:43 PM

I'm using recv.c example in Qpid Proton C library that have the following loop to receive messages :

while(pn_messenger_incoming(messenger))
    {
      pn_messenger_get(messenger, message);
      check(messenger);

      char buffer[1024];
      size_t buffsize = sizeof(buffer);
      pn_data_t *body = pn_message_body(message);
      pn_data_format(body, buffer, &buffsize);

      printf("Address: %s\n", pn_message_get_address(message));
      const char* subject = pn_message_get_subject(message);
      printf("Subject: %s\n", subject ? subject : "(no subject)");
      printf("Content: %s\n", buffer);
    }

It seems that receiving the message and when the pn_messenger_incoming statement is executed the second time, the library finds connection closed by broker and then returns above error.

Why ?

Paolo.
