Jungbae Jun commented on KAFKA-5778:
------------------------------------
I patched my kafka version by 0.10.2.1 and the problem has not been occurred
for 2 weeks.
> Kafka cluster is not responding when one broker hangs and resulted in too
> many connections in close_wait in other brokers

> In a cluster of 3 brokers , one of the broker(Broker-1 ) is hanged and from
> then other two brokers has connections in close_wait for java client
> producer/consumer and also even some broker to broker connections are in
> close wait among those two brokers.
> Kafka Version : 0.10.0.1
> In logs I found replica fetcher thread connection refused exceptions:
> In broker 0 : replica fetcher 0-1, replica fetcher 0-2
> In broker 2 : replica fetcher 0-0, replica fetcher 0-1
> In broker 1 : It was hung no logs were available at that time.
> We tried restarting broker- 2 kafka and then it was not successful as it
> terminated saying zookeeper timeout
> then we tried restarting broker- 0 kafka and we got the same error
> Broker -1 was hang so , we could not login even into it
> so we restarted broker -1 machine
> then we restarted all zookepers and then kafka brokers now everything is fine
