[jira] [Created] (KAFKA-3773) SocketServer inflightResponses collection leaks memory on client disconnect

Jason Gustafson created KAFKA-3773:
--------------------------------------

             Summary: SocketServer inflightResponses collection leaks memory on client disconnect
                 Key: KAFKA-3773
                 URL: https://issues.apache.org/jira/browse/KAFKA-3773
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.9.0.1, 0.9.0.0
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


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.
