Gordon Sim commented on QPID-3264:
----------------------------------
I think workaround 1 is a good one. We should document that somewhere, or
perhaps even see if we can set the default appropriately in code.
> Channel exception: session-busy: Session already attached

> Key: QPID-3264
> URL: https://issues.apache.org/jira/browse/QPID-3264
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Client
> Affects Versions: 0.8
> Environment: Broker on RedHat 5.6 64bit; Client on Windows 7.
> Reporter: Barys Ilyushonak
>
> While client reconnect we got:
> 2011-05-11 16:15:07 error Channel exception: session-busy: Session already
> attached: .a7235961-c1f9-4a76-923c-ff06b09ad0c5
> (qpid/broker/SessionManager.cpp:55)
> To reproduce:
> Start linux broker on default port 5672. Create durable queue and exchange.
> Start the broker. Start client. Client sent the first message. We sow this
> message on the broker. After that enable IPTABLES to reject the port. Client
> still sent messages, but there was no new messages on the broker. After that
> disable IPTABLES to reject the port.
> It is important do not restart the client.
> After that we have got the error in the broker log.
> On the client:
> std::auto_ptr<qpid::messaging::Connection> m_connection
> m_connection.reset(new Connection(m_url));
> m_connection->setOption("reconnect", true);
> We limit network access on the broker machine. To close the port we use:
> iptables -A INPUT -p tcp -s 10.30.24.181 --dport 5672 -j REJECT
> where 10.30.24.181 - windows client IP
> to enable access we use:
> iptables -D INPUT -p tcp -s 10.30.24.181 --dport 5672 -j REJECT
