As promised I have created a c++ test program (TestProducerBug) that will
create up to X producers. The class that does the work is
(TestProducers.cpp).
I am created a C# test program (TestConsumerBugCSharp) that will create up
to X consumers using a MessageListener. The class that does the work is
(TestConsumers.cs).
I have created a C++ test program (TestConsumerBug) that will create up to X
consumers. The class that does the work(TestConsumers.cpp).
Here is some information on my setup.
Compiler MS 2005.
ActiveMQ
Running ActiveMQ 5.0 Dated Dec 7th 2007. It is running on windows 2003
Server 64 Bit.
Running Java 1.6.0_02 this version of Java is 64 bit. (Problem happens even
on a 32 bit version of JAVA).
ActiveMQ Settings
Broker Settings (persistent="false" advisorySupport="false")
Topic Policy
<policyEntry topic="Test.>" producerFlowControl="true">
<!-- lets force old messages to be discarded for slow consumers
-->
<pendingMessageLimitStrategy>
<constantPendingMessageLimitStrategy limit="5"/>
</pendingMessageLimitStrategy>
<messageEvictionStrategy>
<oldestMessageEvictionStrategy />
</messageEvictionStrategy>
</policyEntry>
Client API's
CPP activemq-cpp-2.1.2-src
C# ApacheActiveMQ (Not sure the version but latest trunk).
When running these test remember to stop and restart the broker each test as
the test can and will cause the broker to hang.
Tests 1 -3 will show what is happening between the CPP and C# API.
Test 4 will show what happens to a producer when a consumer is in a break
point in the MessageListener.
Test 1
To recreate the issue build and run
TestProducerBug
TestConsumerBugCSharp.
If you set the number of producers and clients to 10 you should see the
problem happen in less then 5 min (About 2,000 messages per consumer).
The producer will throw an exception place a breakpoint on the catch block
in the ThreadProc. you will see the following information.

Test 2
Now if you build and run
TestProducerBug
TestConsumerBug
These tests both use the C++ API and works as expected
Test 3
In the CPP program TestProducerBug you will find a sleep commented out in
the ThreadProc uncomment this line. Build Program.
Build TestConsumerCSharp.
You will find with the 100 ms sleep the application is stable.
Test 4
Build TestProducerBug remember to comment out the sleep
Build TestConsumerCSharp.
Place a breakpoint on the MessageListner in the C# program.
In very little time the producer will throw an exception.
