> This error occurs when nifi is unable to start an controller service that is supposed to be in an enabled state.
> For example, if the StandardSSLContextService is running, but the underlying keystore file it relies on is removed from the filesystem, nifi will be unable to successfully start it on a nifi restart.
> When nifi is shutdown the following error is in nifi-app.log:
> {code}
