[zeromq-dev] Zeromq dropping messages

Hi folks,

I am using zeromq in a publisher subscriber mode with ZMQ_NOBLOCK option. At
very high rates of publisher I find that messages are being dropped by
publisher without reporting the failure to me.
(ie zmq_send returns success, when the message is not delivered at the
subscriber). I understand that zeromq delivers messages asynchronously, but
dropping messages without reporting looks a little strange. Am I doing
something wrong here or is that the default behavior?

Also if I have a mix of fast and slow subscribers, would zeromq report
success for the msg if the buffers were full for a particular subscriber.
