Summary: QMF method "queueMoveMessages" loses one message when
moving to full queue
Key: QPID-5116
URL: https://issues.apache.org/jira/browse/QPID-5116
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.22
Reporter: Pavel Moravec
Priority: Minor
Invoking QMF method "queueMoveMessages" where destination queue can't handle
all moved messages due to its capacity, one message is lost.
Reproducer:
$ qpid-receive -a "tinyQueue; {create:always, node:{ x-declare:{
arguments:{'qpid.max_count':100}}}}"
$ qpid-send -a "fromQueue; {create:always}" -m 1000
$ qpid-tool
