 This status is returned when the Broker detects a stale sequence value during bootstrap or during health check. The sequence value is changed each time a role change occurs. A site that is unavailable for the role change operation will end up with a stale sequence number. Should that site attempt to rejoin the configuration, the broker will determine that it missed a role change and disable that site. The broker permanently disables the site since it may no longer be a viable standby site for the new primary.
