Got error produce response with correlation id 16 on topic-partition

[barryzhounb]

During Kafka producer sends messages to Strimizi Kafka cluster on OpenShift, I saw a bunch of warnings as following.

I am wondering what it means? What is the root cause (seem it complain NETWORK_EXCEPTION, is it true)? In this case, will message in correlation id 16 be lost Or "Kafka retry" can correct them such that message is not be lost?
