> Key: QPID-6654
> URL: https://issues.apache.org/jira/browse/QPID-6654
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: qpid-cpp-0.34
> Environment: CentOS 6.3 x86_64
> Reporter: Clive Lilley
> Priority: Minor
>
> Running the 0.34 cpp broker on a CentOS 6.3 installation and noticed that
> when the --mgmt-enable is set to false the broker core dumps when
> qpid-receive attempts a connection
> If I remove the --mgmt-enable option the broker runs fine.
