> The framework initialization process includes asynchronous enabling of Controller Services using a Runnable command submitted to the shared Timer-Driven {{ScheduledExecutorService}}. The {{StandardControllerServiceNode}} {{enable}} method initiates the command, which first checks the Validation Status of the Controller Service before calling {{OnEnabled}} methods.
> In deployments with multiple Controller Services, the enabling process can take several minutes while waiting on asynchronous validation to be completed. The Runnable enable command reschedules itself when the Controller Service is not valid, waiting for asynchronous validation to be completed. As a result of waiting for validation, the enable command retries multiple times and does not complete until after Controller Service validation.
