Matthias J. Sax resolved KAFKA-7133.
------------------------------------
Resolution: Abandoned
> DisconnectException every 5 minutes in single restore consumer thread
> ---------------------------------------------------------------------
>
> Key: KAFKA-7133
> URL: https://issues.apache.org/jira/browse/KAFKA-7133
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.1.0
> Environment: Kafka Streams application in Kubernetes.
> Kafka Server in Docker on machine in host mode
> Reporter: Chris Schwarzfischer
> Priority: Major
>
> One of our streams applications (and only this one) gets a
> {{org.apache.kafka.common.errors.DisconnectException}} almost exactly every 5
> minutes.
> The application has two of
> KStream -> KGroupedStream -> KTable -> KGroupedTable -> KTable
> aggregations.
> Relevant config is in Streams:
> {code:java}
> this.properties.put(StreamsConfig.PROCESSING_GUARANTEE_CONFIG,
> StreamsConfig.AT_LEAST_ONCE);
> //...
> this.properties.put(StreamsConfig.NUM_STREAM_THREADS_CONFIG, 2);
> this.properties.put(StreamsConfig.CACHE_MAX_BYTES_BUFFERING_CONFIG, 1024 *
> 1024 * 500 /* 500 MB */ );
> this.properties.put(ConsumerConfig.MAX_PARTITION_FETCH_BYTES_CONFIG, 1024 *
> 1024 * 100 /* 100 MB */);
> this.properties.put(ConsumerConfig.FETCH_MAX_BYTES_CONFIG, 1024 * 1024 * 50
> /* 50 MB */);
> {code}
