First thought is to make sure that you insert the address of the receive endpoint into the AVs and use that entry as the destination address.
I am adding the receive endpoint address and when I dump the contents of the AV on all nodes, each have matching address lists.
One thing - if I have to bind the AV to the endpoint and then add some addresses later - does this matter - or does the binding take a copy? It worked ok when I had a common endpoint for send+recv so I don't see why it should make a difference having two endpoints.
Also, I use the same address vector in both send and recv endpoints, I presume this is fine too.
I'm baffled because I've spent a couple of days stepping through my code and can't see anything wrong.
Thanks for any pointers
