Cause
This error occurs when:
A secondary database attempts to connect with an SDS primary database using the same name as another secondary database that is already connected.
Two or more secondary databases are configured with the same name specified in the MyName parameter in the [SyncDbService] section of the JADE initialization file.
A secondary database disconnects from a primary database (for example, due to a temporary network error) and then attempts to reconnect before the primary database has completely processed the disconnect event.
Action
Ensure that each secondary database in an SDE has a unique name.
