OK - these sequence numbers are unrelated to the send/recv tags, right?  I’m 
happy to do any further debugging.  I can’t share code, since we do have access 
but it’s not open source, but I’d be happy to test out anything you can suggest.

                                                                                
                thanks,
                                                                                
                Noam
