Christian Schneider commented on CXF-3230:
------------------------------------------
I was able to reproduce the issue with cxf 2.3.1 and ActiveMQ 5.4.2 as well as
ActiveMQ 4.0.2.
At the moment I have no idea though what is the cause of the problem. The Heap
Memory and JVM THreads do not seem to grow. Only the native threads seem to
grow.
When googling the problem that exception "unable to create new native thread"
seems not uncommon in ActiveMQ. As the problem is also reported for other jms
providers it can´t be a pure ActiveMQ problem though.

> Project: CXF
> Issue Type: Bug
> Components: Transports
> Affects Versions: 2.3.1
> Environment: Linux, ActiveMQ 5.4.2 and HornetQ 2.1.2

> This issue was found both when testing with ActiveMQ 5.4.2 and HornetQ 2.1.2
> as JMS provider. The JMS settings is set in the WSDL file:
> <service name="TestJMS">
> <port binding="tns:TestBinding" name="Test">
> <address destinationStyle="queue"
>
> jndiConnectionFactoryName="ConnectionFactory"
>
> jndiDestinationName="dynamicQueues/messageDestination"
>
> xmlns="http://cxf.apache.org/transports/jms";>
> <JMSNamingProperty
> name="java.naming.provider.url"
> value="tcp://localhost:61616?jms.watchTopicAdvisories=false"/>
> <JMSNamingProperty
> name="java.naming.factory.initial"
> value="org.apache.activemq.jndi.ActiveMQInitialContextFactory"/>
> </address>
> </port>
> </service>
> The issue was found when performing a test with a server and a client both
> created with CXF. The client has an infinite loop that performs a request on
> the server and waits for a response before the next iteration is executed.
> After a couple of thousands of request response iterations have been
> performed the JMS provider starts to get very slow and ActiveMQ gets out of
> memory if the test is run long enough. First I thought it was a configuration
> problem with the JMS provider or a bug in ActiveMQ, but because the same
> problem exists both with HornetQ and several configurations of ActiveMQ it
> seems like it is a problem with CXF.
> When monitoring ActiveMQ with jconsole it can be seen that when ActiveMQ is
> set to not use a thread pool
> (-Dorg.apache.activemq.UseDedicatedTaskRunner=true), the number of threads
> grows while the test is running and no threads seem to be deallocated. When a
> thread pool is used the number of threads is quite constant but the amount of
> memory on the heap still grows. No leak is observed when a response queue is
> specified with jndiReplyDestinationName. So when a temporary queue should be
> used to send back the replay it seems like one replay queue is created for
> every replay and they never get removed.
