----------------------------------
Summary: Attempting to settle a rx multiframe message part way can
cause connection drop
Key: PROTON-2050
URL: https://issues.apache.org/jira/browse/PROTON-2050
Project: Qpid Proton
Issue Type: Bug
Components: proton-c, python-binding
Affects Versions: proton-c-0.28.0, proton-c-0.27.1
Reporter: Ken Giusti
Fix For: proton-c-0.29.0
Unsure if expected behavior:
If a receiver settles an inbound message before all frames have arrived, any
buffered frames (including frames buffered in the sender) that arrive after the
settlement causes the connection to close. See the following router log:
