             Summary: [qpid-cpp] Client open connections to broker and waits forever
                 Key: QPID-8221
                 URL: https://issues.apache.org/jira/browse/QPID-8221
             Project: Qpid
          Issue Type: Bug
          Components: C++ Client
    Affects Versions: qpid-cpp-1.38.0
         Environment: * qpid-cpp 1.38 c++ client/broker
 * AMQP 0-10
 * RHEL 7.5
            Reporter: Chen Wan
         Attachments: qpidcpp_client_connect_timeout.patch

I have a problem with qpid-cpp C++ clients stuck on the open connection call while reconnecting with the broker.   It is a rare event, sometimes takes weeks or months to happen.  But when it occurs, I have to manually restart the client process in order to re-establish the broker connection. 

I have summarized the details of this issue in this mailing list post: http://qpid.2158936.n2.nabble.com/Open-connection-to-broker-waits-forever-td7678381.html

Attached is a patch (qpidcpp_client_connect_timeout.patch) to add a timeout to qpid-cpp client's open connection call.  A new option called "connect-timeout" can be used to specify how long to wait for the connection::open call in seconds.  When the "connect-timeout" is set, qpid-cpp client calls "waitFor" with a timeout. 

I have tested it in my environment, and it seems to be able to time out properly when the open call gets stuck.
