Description
If the no-op message is not received before a specific interval, the consumer will disconnect the connection causing rebalance to hang.
It was noted that the step function of that particular producer wasn't visited at all, there by not sending the no-op and thus causing the consumer to disconnect. This is because we were failing to notify the producer connection.
Logs filled with timeouts in checkpoint persistence:
