Description

When broker was sending a FetchResponse it is possible that the data to be sent back is truncated. In this case, a KafkaException will be thrown. This exception is caught by processor and the selector will be sending the message in a tight while loop. It will continue doing this until the socket is closed by the client due to request timeout.

We should have a max retry for the response send.
