If configurationResourcePollingFrequency is not specified services are never reloaded. If a configuration resource fails to load because it can't be read, is invalid, or for any other reason the IdP will continue to use the previous configuration and try to read the file again after configurationResourcePollingFrequency. If the configuration file fails to load a number of times equal to configurationResourcePollingRetryAttempts, the IdP will stop trying to reload the file. A restart will be required to re-enabling polling.
