---------------------------------------------------------

Updated the affects version. Yes, I think it is exactly the same issue with KAFKA-7044.

 

In my case, I have a kafka consumer in streams processor, which consumes 128 partitions from 9 topics , and sometime I got this exception when I run the following command - it seems once it happened it will never recover unless I restart the streams application.

 
{code:java}
kafka-consumer-groups --bootstrap-server $BROKER_LIST --command-config consumer.properties --describe --group $CONSUMER_GROUP_NAME {code}
