Alexandre,
The fix to DISPATCH-343 is in the RC4 update. Have you tried to
reproduce your symptom using this release candidate?

Alexandre,
I'm looking into this. I think it may be related to DISPATCH-343. The
problem is related to the management of the lifecycle of deliveries.
When the above is fixed, you should re-test your reproducer.

Hi guys,
I have a crash which I can reproduce reliably on the dispatcher at trunk.
A dispatcher is configured to pull messages from a QPID-java broker
queue for subscribing.
qdmanage -b localhost:2727 create --type=connector name=broker
role=on-demand addr=localhost port=5672
qdmanage -b localhost:2727 create --type=address prefix=myqueue
waypoint=true
qdmanage -b localhost:2727 create --type=autoLink addr=myqueue dir=in
connection=broker
The queue on the broker is filled with a large quantity of messages.
Reading the messages from the dispatcher, while creating a new
connection for each consumer crashes.
@Test
public void dispatcherSend() throws JMSException {
int consumers = 1000;
String remoteURI = "amqp://dispatcher-host:2727";
for (int i = 0; i < consumers; i++) {
System.out.println("On consumer " + i);
ConnectionFactory connectionFactory = new
JmsConnectionFactory(remoteURI);
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("atr.queue");
MessageConsumer consumer = session.createConsumer(queue);
consumer.receive(1000);
connection.close();
}
}
I have seen two different assertions fail with these crashes:
qdrouterd:
/src/new/atrufanow/qpid-env/qpid-dispatch/src/router_core/connections.c:474:
qdr_link_cleanup_CT: Assertion `(unsettled).size == 1' failed.
qdrouterd:
/src/new/atrufanow/qpid-env/qpid-dispatch/src/router_core/transfer.c:114:
qdr_link_process_deliveries: Assertion `(link->undelivered).size == 1'
failed.
Host is linux Redhat and compiler is GCC 4.4.7
