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
