Hey Karl, I have a very similar setup (3 kafka 0.7.2 brokers, 3 ZK 3.4.3 nodes) that I'm running right now and am getting the same error on the producers. Haven't resolved it yet:
ERROR ProducerSendThread--1585663279 kafka.producer.async.ProducerSendThread - Error in handling batch of 200 events java.io.IOException: Connection reset by peer ... For me these errors appear to be coupled with other errors like this: kafka.producer.async.AsyncProducer - Event queue is full of unsent messages, could not send event: As I understand it, this happens when you are producing faster than the brokers can persist the messages. It's possible these are two different issues... Anyway I've been doing a lot of work on this this afternoon so I may have more information later. Someone else probably knows more though.
