Helen Huang closed AMQCPP-311.
------------------------------
Resolution: Won't Fix
Sorry but I just found out that is the issue of our application in stead of
CMS. Thanks for looking into it.

> Key: AMQCPP-311
> URL: https://issues.apache.org/activemq/browse/AMQCPP-311
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: CMS Impl
> Affects Versions: 3.2.2
> Environment: Windows. ActiveMQ broker 5.3.1.
> Reporter: Helen Huang
> Assignee: Timothy Bish
> Priority: Blocker
>
> In our application, we are using a CmsTemplate
> (activemq::cmsutil::CmsTemplate) to receive messages. For each received
> message, we first create a task then put it into the threadpool
> (decaf::util::concurrent::ThreadPool) for processing. We expect the worker
> threads are independent from the receiving functionality of the CmsTemplate.
> While a receiver is waiting for new messages, the worker threads should be
> able to process the messages that have been received already. However, that
> is not we observed. The worker threads seem to be put into sleep until the
> receiver timeouts.
> The following is the log we have created. you will see that we received five
> messages. The last message was received and enqueued at 14:13:20 (by thread
> 0BB0), It was only processed at 14:13:30 (by thread 0FDC), at/after a receive
> timeout (on thread 0BB0) . The waiting time seems to be equal to the receive
> timeout which was 10 seconds. We have repeated the test by setting the
> receive timeout to 200ms,1s, 3s, 5s, and 10s. We observed the same behavior
> with each test. The configuration for the threadpool was: MaxThreads 20,
> BockSize 5, ReservedThreads 10. This is a critical issue for our application.
> Hope you will be able to look into it soon. Your help is highly appreciated!
