> If I run
>    org.activemq.jms.StandaloneApp 200 1
> it works fine. Tried it 5 times, so sent 1000 messages altogether
> If I run
>   org.activemq.jms.StandaloneApp 250 1
> it fails. The master is fine, but the slave still has pending messages on "queue.A". (43 in my last run)
> It reported 407 received messages. (the first 200 + 207 of the last run)
