Kafka Broker Not Responding

[SenthilKumar K <se...@gmail.com>]

Hello Kafka Experts,

     We are currently facing issue on our 3 node Kafka Cluster , one of the
broker is not responding to any queries. I've checked logs but founding
nothing related to this problem.


Kafka Version: 1.1.0

*ERROR [Consumer clientId=consumer-1, groupId=console-consumer-21688]
Offset commit failed on partition logs-28 at offset 0: The request timed
out. (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)*


Partition : logs-28 is actually resides on the broker which is not
responding... If i restart the broker it will start responding but would
like to figure exact cause on why out of 3 brokers one broker is failing .
