huxi commented on KAFKA-4739:
-----------------------------
Seems that FETCH requests time out every 40 seconds and 40 second is the
default value for config `request.timeout.ms` of the new consumer. Could you
make sure if your settings take effect? And why do you set a probably large
timeout value? Poor network condition?
> KafkaConsumer poll going into an infinite loop

> Key: KAFKA-4739
> URL: https://issues.apache.org/jira/browse/KAFKA-4739
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.9.0.1
> Reporter: Vipul Singh
>
> We are seeing an issue with our kafka consumer where it seems to go into an
> infinite loop while polling, trying to fetch data from kafka. We are seeing
> the heartbeat requests on the broker from the consumer, but nothing else from
> the kafka consumer.
> We enabled debug level logging on the consumer, and see these logs:
> https://gist.github.com/neoeahit/757bff7acdea62656f065f4dcb8974b4
> And this just goes on. The way we have been able to replicate this issue, is
> by restarting the process in multiple successions.
