Hi, The broker is in slave mode when another process/broker has the lock on kahadb.
If you check in kahadb folder, you should have a lock file (in your case, it seems to be in /var/tmp/amq/data), so, either you have already a broker running, either the broker doesn’t have to take/create the lock in the kahadb folder.
