Write to Topic when one is not created
I seem to be sending messages to a topic when in fact i'm not creating one.
If I run activemq-admin query, i see my queues that i've created but there
also seems to be a topic created for each queue, that i've created in my
code i never call createTopic, always createQueue. I see the topics
EnqueueCount grow, I have no idea why.
Does anyone know what is going on?

Note that setting does not affect the JVM heap size; try changing that.

Maybe you need to increase the heap size? Which heap is running out,
the broker or the jms client?

You were right, when i disabled advisory support those topics stopped showing
up. I am getting Out of Memory errors and I thought that that might be a
problem, messages being queued but not consumed. I am using a Snapshot
version of 4.2, are you aware of any known issues that would cause an java
heap out of memory problem?
Thank you

Hi,
I believe what you're seeing are advisory topics which are automatically
created by default by activemq to send advisory messages to monitor the
behavior of the system (ie. starting of connections, creation of
destinations, etc).
http://activemq.apache.org/advisory-message.html
Btw, you can also disable advisory support by setting it to false in
your broker configuration :
<broker brokerName="localhost" useJmx="true" advisorySupport="false"
.... >

Jonas
