> Prior to 0.10, we did not clean the {{inflightResponses}} collection maintained by each processor when a client disconnected. This causes a quickly growing memory leak since that collection maintains a reference to the pending response, which can be quite large in the case of fetches. This was fixed in KAFKA-3489 for 0.10, but we should ensure that 0.9 is patched as well.
