Hi John,

When you say, "the messages are all being consumed," do you mean that
there is a receiver app that is getting them all?  If your sender app
is joining the destination group(s), then it also needs to receive
those messages to clear the queue at the Spread daemon for its
connection.  If you don't want to have to do that, you can (a) not
have the sender join the destination groups, since Spread supports
open group semantics, or (b) send your messages with the SELF_DISCARD

Please ignore this if my assumptions about your sender app aren't correct.
