Assignee: Alan Conway (was: Cliff Jansen)
> [c++] Proton C++ client silently retains presettled messages
> ------------------------------------------------------------
>
> Key: PROTON-1461
> URL: https://issues.apache.org/jira/browse/PROTON-1461
> Project: Qpid Proton
> Issue Type: Bug
> Components: cpp-binding
> Affects Versions: 0.17.0
> Environment: Fedora 25
> Test message source: Qpid Dispatch Router with address that has
> 'distributionMode: multicast'
> Test client: example simple_recv.cpp
> Reporter: Chuck Rolke
> Assignee: Alan Conway
> Fix For: proton-c-0.18.0
>
>
> With distributionMode 'multicast' the router sends messages presettled. In
> this mode the simple_recv program memory grows without bound until OOM.
> Switching the router to use distribution mode 'closest' causes the router to
> send messages unsettled. In this mode the same simple_recv client sends back
> a disposition and program memory use is normal.
> A brokered connection, like to Apache Artemis, behaves normally with
> unsettled messages and dispositions for each.
> For comparison example program proton-0.18.0/examples/python/simple_recv.py
> receives router multicast presettled messages and experiences no memory
> growth.
