[jira] [Updated] (PROTON-1461) [c++] Proton C++ client silently
retains presettled messages
[ https://issues.apache.org/jira/browse/PROTON-1461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justin Ross updated PROTON-1461:
--------------------------------
Fix Version/s: proton-c-0.18.0
> [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: proton-c-0.18.0
> 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: Cliff Jansen
> 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.
