The error indicates that your replication is falling behind,this exception doesn't really imply that a broker is down, it can likewise mean that an excessive number of copies for that topic partition have fallen behind the leader with some reason.

Configure your replication higher https://cwiki.apache.org/confluence/display/KAFKA/Replication+tools

You probably need more replicas for faster throughput
