The identification and deletion of expired temporary reservations is performed by a Name Arbiter Bean method called by this scheduled service. This scheduled service runs once a day.

Typically each temporary reservation is removed as soon as it expires by a javax.ejb.Timer task scheduled at the time the temporary reservation is created, if it has not been removed explicitly by the client system. However, this Timer task is deleted if JBoss is restarted, so this scheduled service is required to clean up any temporary reservation that failed to be removed by its Timer task.
