How do subscribers request retransmissions? Is this entirely up to the application, or is it supported by the message library?
You can configure the retry mechanisms in epgm itself but those can get overrun too. If you need more guarantees on delivery, take a look a the guid at zguide.zeromq.org and read up on the "clone pattern."
