Pavel Moravec commented on DISPATCH-37:
---------------------------------------
One particular memory leak: in setup_incoming_link:
Single dispatch router running and connecting+disconnecting any link from a client. valgrind logs:

> Key: DISPATCH-37
> URL: https://issues.apache.org/jira/browse/DISPATCH-37
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Container
> Affects Versions: 0.1
> Reporter: Pavel Moravec
> Attachments: out01.log
>
>
> Valgrind reports various memory leaks after very basic usage of Dispatch router. For basic scenario, have 2 routers A<->B and send messages from bouncing producer connected to A to a bouncing consumer connected to B. Attached is valgrind output for that.
> Some particular memory leaks to be commented later on.
