> A Pure Master Slave Broker is used to increase availability of the broker. 
> More information about it can be found in the activemq documentation:
> http://activemq.apache.org/pure-master-slave.html 
> In a test we simulated Master failure through killing the process with kill -9.
> Here is the log output from the worker node:
> INFO  FailoverTransport              - Successfully connected to tcp://XXX1:61616
>  Here I stopped the master broker process with kill -9 
> WARN  FailoverTransport              - Transport failed to tcp://XXX1:61616 , attempting
to automatically reconnect due to: java.io.EOFException
> WARN  FailoverTransport              - Transport failed to tcp://XXX1:61616 , attempting
to automatically reconnect due to: java.io.EOFException
> WARN  FailoverTransport              - Transport failed to tcp://XXX1:61616 , attempting
to automatically reconnect due to: java.io.EOFException
> INFO  FailoverTransport              - Successfully reconnected to tcp://XXX2:61616
> INFO  FailoverTransport              - Successfully reconnected to tcp://XXX2:61616
> INFO  FailoverTransport              - Successfully reconnected to tcp://XXX2:61616 
> Afterwards the client was restarted but got a time out error during initialize.
> During initializes it sends a message to the worker nodes input queue, but this
> message if never retrieved.
> I used the activemq web interface to get some information about the message:
> Command     2001
> MessageFrom     ID:XXXX-51032-1257865414664-0:1:1
> ServerURI     failover:(tcp://XXX1:61616,tcp://XXX2:61616)?randomize=false
> MessageType     3000
