possibly you are hitting https://issues.apache.org/jira/browse/KAFKA-3042

What is your Kafka version? Is your topic or other underreplicated?

This could be due to a network connection temporary glitch. During the glitch the zookeeper nodes likely couldn't reach each other which leadto topic underreplication issues.

You could restart brokers as a workaround.
