-----------------------------------
Summary: Socket server selector can stuck on one send in tight
loop.
Key: KAFKA-2936
URL: https://issues.apache.org/jira/browse/KAFKA-2936
Project: Kafka
Issue Type: Bug
Reporter: Jiangjie Qin
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.
