ActiveMq Topic with multiple consumers

Hello all! I'm working on this problem a lot of time now and can't seem to
find any final solution to it.
I have a message producer that should work as a broadcaster, posting
messages on two different topics. The publisher's posting process follows
the flow : 

-Creating connection to the factory and starting it.
-Creating session
-Creating Message Producer by using the session and a given topic Name
-Sending n* of messages
-Waiting n seconds
-Closing producer,session,connection

Then i have 3 consumers subscribed to those topics by using the following
configuration(each consumer has it's own id and durableSubName):

<route id="consumerOneRoute">
	<from
uri="activemq:topic:topicName?clientId=consumerOneId&durableSubscriptionName=ConsumerOneName"
/>
				<bean ref="consumerBean" method="processMessage" />
</route>

The fact is that my consumers don't always receive the messages, atleast not
all of them. Sometimes two of the consumers get all the messages and the 3rd
one don't get any, sometimes random consumer receive random number of
messages and so on... 
One more fact that i noticed is that if i stop the broker and start it
again, the consumers will receive the missing messages, and i really can't
understand why won't that happen during the 1st lifetime of the broker.
Would anyone be so kind and try to aid me?

Thanks,
George.

P.S : I was thinking about using virtual topics though since my main purpose
is to have a broadcasting producer that will allow other consumers to attach
in the future i don't want to have the need of modifyin' the producer
everytime by adding another virtual branch to the main topic.
