Christian Schneider commented on CXF-2002:
------------------------------------------
We are currently using the Spring DefaultMessageListenerContainer.
http://static.springframework.org/spring/docs/2.0.x/api/org/springframework/jms/listener/DefaultMessageListenerContainer.html
It supports setting the maxConcurrentConsumers to limit the number of listener
threads.
It start a task for each message with the SimpleAsyncTaskExecutor.
http://static.springframework.org/spring/docs/2.0.x/api/org/springframework/core/task/SimpleAsyncTaskExecutor.html
This will by default start an unlimited number of threads. But you can set a
limit by using the concurrencyLimit property. Currently this can only be set by
using the new config style JmsConfigurationFeature and injecting a
SimpleAsyncTaskExecutor.
When using the old config style setting the concurrencyLimit is not possible. I
will add a JmsConfiguration property for this that can be also be set by using
the sessionPool highWaterMark in the old config style.
Do you think this will solve the problem?

> Project: CXF
> Issue Type: Improvement
> Affects Versions: 2.0.10
> Reporter: Ron Gavlin
>
> Currently, the server-side async jms transport has no mechanism to throttle
> consumption of incoming messages. This becomes problematic in scenarios where
> a large backlog of messages exists on the input queue. In this case, it is
> likely that the cxf server will overload its internal work item queues
> resulting in problems. A dynamic throttling mechanism on the async jms server
> is required to avoid this problem.
