Hi there! It was probably sent to the wrong list? Wish I can get some answer here.

To: us...@kafka.apache.org Hi there! We have noticed that when committing requests are sent intensively, we receive IllegalGenerationId. Here is the settings we had problem with: session-timeout: 30 sec, heartbeat-rate: 3 sec. Problem resolved by increasing the session timeout to 180 sec. So I suppose, due to whatever reason (either the client didn't send heartbeat, or the broker didn't process the heartbeats in time), the session was considered dead in group coordinator. My question is: why commit requests can't be taken as an indicator of member being alive? hence not to kill the session. Regards -Zaiming
