The crash is due to the client's request not completing until after the servers response has been fully received and the server has closed the connection to indicate EOM.
What appears to be happening is the client's entire message body has arrived and been forwarded to the server but the message is not marked "receive complete" (next stream data == "need more"). The server sees the entire message, unaware that the corresponding AMQP message is incomplete, and sends its response and closes the connection. After the connection is closed the core signals the request message is complete and schedules qd_connection_process which attempts to finish up the now deleted request.
