Resolution: Fixed
> memory grows on a long-lived connection when links are opened and closed
> ------------------------------------------------------------------------
>
> Key: DISPATCH-1069
> URL: https://issues.apache.org/jira/browse/DISPATCH-1069
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Container
> Affects Versions: 1.2.0
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Major
> Attachments: link-leak.c, link-leak.py
>
>
> The attached reproducers link-leak.c and link-leak.py open and close links repeatedly on the same connection. This causes the routers memory use to grow.
> Massif shows that the memory is due to pn_link_t and related objects. PROTON-905 describes an old bug where link information is leaked but experiments show this is not happening with modern proton.
> I suspect the growth is due to dispatch sometimes failing to call pn_link_free() but investigation is still ongoing.
