The same issue (https://issues.apache.org/jira/browse/AMQCPP-369) is
applicable to Solaris too.
So, it's not Mac-specific at all, and I suggest to try 3.4.1 on

Consumers always belong to some session; session is thread-specific

It seems like you hit prefetch limit (the default prefetch size is
1000). Try setting prefetch size to something larger for the
particular connection or consumer used by your 'queue sorter'.

We use UTF-8 successfully in ActiveMQ's TextMessage since activemq-cpp-3.0.x.
In particular, we UTF-8 between C++ and Java clients.

As far as I remember, even much newer Visual C++ 2003 (VC7.1) isn't supported.
Hence VC6 is not supported too.

It's fine without correlation ID as long as the requesting side

You need resource adapter in order to connect your MDBs to ActiveMQ
broker. No matter whether you are embedding the broker, or not.
By the way, if you need to connect your MDBs to more than one brok

You should configure property "ServerUrl" of ActiveMQ Resource Adapter
(RA) to connect to your standalone ActiveMQ instance.

Because the connection is not closed actually, it is just returned to the pool.
If I understand correctly, the following kinds of ActiveMQ objects
involve sync request to ActiveMQ broker

Hello!
I use JBoss, ActiveMQ resource adapter (RA), and a message-driven bean
(MDB) with a persistent queue.
I need to be able to leave a message in queue if something bad
happened inside method onMessage() of my MDB.
The question is how to achieve it?
I looked into the source of ActiveMQ RA, and
Hello
We have a message-driven bean in JBoss with ActiveMQ resource adapter (RA).
It seems like ActiveMQ RA doesn't support CLIENT_ACKNOWLEDGE mode. It
supports only DUPS_OK_ACKNOWLEDGE and AUTO_ACKNOWLEDGE modes.
Basically, I need to be able to leave a message in queue if something bad
happened

- CMS (ActiveMQ-CPP) on the server (responder) side.
