Chuck Rolke commented on DISPATCH-1124:
---------------------------------------
If only a single receiver is attached to the green router then it will receive
indefinitely. As soon as a second receiver is attached then the green router
fails.
If the standard qpid-proton cpp simple-send example is the sender then it will
receive indefinitely with one or two receivers. When simple-send is modified to
send a 1443-byte text string then the green router fails.
The longer message wakes up the "message streaming" feature of dispatch
qd_message_send. The multiple receivers wakes up the message fanout and shared
message content features. This test exercises streaming, fanout, and shared
content.
