> NiFi will not enable all controller services during startup when there are
> additional referenced controller services within a controller service.
> Specifically, this was observed when the referenced controller services were
> dynamic properties.
> The enabling process correctly enables referenced services first. However,
> during the enabling process, all referencing components are validated. This
> creates a situation where the parent controller service is repeatedly
> validated for every child controller service. And, part of the validation of
> the parent is to validate the child. The circular validation will eventually
> block; controller services are not properly enabled; NiFi does not complete
> the startup process.
