ConsumerFetcherThread problem

Hi

I have some problem
I have used kafka_2.9.1-0.8.2.2.

kafka was operating normally about 2 weeks

but I execute a command bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic <topic name>
I got error message
2016-01-30T11:07:14.058+0800 k.c.ConsumerFetcherThread [ERROR] [ConsumerFetcherThread-Log3Consumer_HPoint-CBT1-hub-1453895126125-e3ef3ec7-0-0], Error for partition [log3,0] to broker 0:class kafka.common.UnknownException
I saw normally message, too

Consumer print error message and normally message.

I don't know why kafka consumer occur error.

Sorry, poor my English.
Thank you.
