KAFKA-5595: Ensure client connection ids are not reused too quickly On the broker, if client ports are reused when response to a closed connection is outstanding, broker may send the outstanding response to a new connection with the reused port. The new connection will end up with correlation id mismatch, requiring process restart. This is also a security exposure since clients receive response intended for the wrong connection.
