transport
[ https://issues.apache.org/activemq/browse/AMQ-750?page=all ]
Hiram Chirino updated AMQ-750:
------------------------------
Fix Version: (was: incubation)
Ning,
Could you supply a junit test case that shows the failaure? Mutithreading issues are complex and hard to describe, a test case would make it very clear.
> multi-threaded issues with failover transport
> ---------------------------------------------
>
> Key: AMQ-750
> URL: https://issues.apache.org/activemq/browse/AMQ-750
> Project: ActiveMQ
> Type: Bug
> Components: Transport
> Versions: 4.0
> Environment: Got the June 6 code using svn, and test is run on Windows
> Reporter: Ning Li
> Priority: Minor
>

> Modified ProducerTool.java into multi-threaded test code:
> This is the peudo code:
> For ( thread 1 to 30 )
> {
> Connection connection = createConnection();
> Session session = createSession(connection);
> Producer producer = createProducer(session);
> sendMessages(producer, 10); //each thread send 10 messages to broker, using url = failover:tcp://localhost:61616
> }
> Please turn on Debug info for log4j, otherwise you will hit other threading issue before this one, when client shutting down, this exception will be thrown:
