    RegisterServerManager is responsible to Register an opcua server on a LDS or LDS-ME server This class takes in charge :

    • the initial registration of a server
    • the regular registration renewal (every 8 minutes or so ...)
    • dealing with cases where LDS is not up and running when server starts. ( in this case the connection will be continuously attempted using the infinite back-off strategy
    • the un-registration of the server ( during shutdown for instance)

    Emitted when the server is trying to registered the LDS but when the connection to the lds has failed serverRegistrationPending is sent when the backoff signal of the connection process is rained
