But in cluster architecture, the lease-database-locker is necessary to avoid multiple brokers running against the same logical database, no ?

But how I ensure that the broker is able to maintain its lock ? You can find attached activemq configuration files. Do you see anything configured incorrectly?

The error message clearly states: BROKER_PROD_1, no longer able to keep the exclusive lock so giving up being a master So, the broker lost its exclusive lock which means it will shut itself down to avoid split brain. This lock is what the master and the slave compete for to ensure only one broker is active at a time. You should ensure that the broker is able to maintain its lock or this will happen.
