Using static Transport - messages not reliably reaching consumers on different machines

I have two brokers configured to use the static transport on two different
machines. 
I have producers sending messages on each of the machines sending messages
to specific topics to the local broker. 
Also, I have consumers that are configured to recieve messages on each of
these boxes as follows - 

Machines - A and B
Producer on A publishes to two topics as follows
message1.A and message2.A
Producer on B publishes to two topics as follows
message1.B and message2.B

Consumer on A listens for following topics
message1.A and message2.* (we want to subscribe to message2 from both the
machines A and B)

Consumer on B listens for the following topics
message1.B and message2.* (we want to subscribe to message2 from both the
machines A and B)

The problem I am facing is the message2 does not get delivered consistently
from the other box. Sometimes it works but sometimes it just does not come
through

Environment - 
Active MQ version 4.1.1
JDK 1.5/1.6

the broker configuration is as below 
<beans>
  
  <broker xmlns="http://activemq.org/config/1.0" useJmx="false">

    <transportConnectors>
      <transportConnector uri="tcp://localhost:62002"/>
      
    </transportConnectors>
    
    <networkConnectors>
          <networkConnector
uri="static://(tcp://host1:62002,tcp://host2:62002)"/>
    </networkConnectors>

  </broker>
  
</beans>

The clients connect using the url tcp://localhost:62002.

Looking forward for a solution here.
Thanks in advance.

Re: Using static Transport - messages not reliably reaching consumers on different machines

Looks like the problem seems to be with the use of wild cards. This certainly
is a defect and probably needs to be fixed. It took quite sometime to really
identify this issue. For now I am working around by not using wildcards in
the topic names. 
I am hoping that this is fixed in the next release.
