So a soft down, for example a brief connectivity issue, will result in the node missing the pushes. It’s not so much a bug, just the way of design. Some other DMQ systems also work similarly and the burden/responsibility is notI placed on the sender to “own” that a member receives and processed the message. This can be done periodically as a safety belt and or when a node notices a connectivity issue may have occurred. It can also not be done for scenarios when it’s not necessary for nodes to be exactly in sync all the time. -- Fred Posner Sent from mobile Phone: +1 (352) 664-3733 >> On Aug 16, 2023, at 3:03 AM, Olle E.
