Brian Roach commented on AMQCPP-220:
------------------------------------
Yeah, that's what I get for trying to optimize the pool usage, sorry.
My original change was to create and destroy a pool within the wait() call.
I'll revert back to that. Using the simpleConsumer example code (or our own) I
never encountered the multiple thread issue.

> Environment: Solaris 10 x86
> GCC (g++) 3.4.6 (from www.sunfreeware.com)

> The API leaks ~ 2MB of memory for every 1 million messages consumed.
> The example consumer in activemq-cpp-2.2.3-src/src/examples/consumers can be
> used as a test bed, it exhibits the behavior.
> It's even worse if you are not using the consumer->setMessageListener( )
> method and are instead directly using the consumer->receive() method in your
> own loop. I dont' have hard numbers but it is somewhere around ten-fold.
> We have an application which is processing ~ 40 million messages per day, and
> will keep growing until the box runs out of memory.
