No. When Ever Slave kicks in...that becomes Master. The Old master becomes slave and will be waiting to get the lock to become master whenever 'the current' master goes down.

To send email or notification we are thinking in use a monitorization tool like nagios or something more light... About the manual restart, i think that you could take a look about linux-heartbeat v2, you could configure services to monitorize and make petitions. One more question, If we have a cluster, if the master goes down, all messages goes to the slave, but, if we start the master again, all messages will send to the master again? 2011/3/29 Nakarikanti, Nageswara <nnakarika...@dwd.in.gov<mailto:nnakarika...@dwd.in.gov>> And, adding my question... When Master Broker goes down, is there any way that administrators get a notification(e-mail etc...) that it went down. Should Only a "manual" restart to bring it up again?

Im using activemq-cpp. The slave broker won't accept connections until it becomes the master so the client won't connect to a slave. It will just keep moving through the list of URI's attempting to connect until a broker becomes available.
