I don't see why a consumer would get blocked if the specified system limits are reached. Only producers should be blocked. The idea is that consumers can still process messages so that more space in the broker is freed to take the next message from the producer. Further I don't understand why a master slave setup would make a difference here. However is the master broker should behave just like an ordinary broker. The slave broker won't even startup and load kahadb as it can't acquire the lock on kahadb. I have not tested this lately but would assume that this property works as explained and only affects the producer, not the consumer.
