> 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: 0.9.0.0, 0.9.0.1
> 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.
