Unrecognized children error seen in DMService.log

You may see these in the normal course of operations. It's really more of a warning than an error, and it generally resolves itself as further syncs occur.
For example, if the interfaces come across in a sync before the parent device. One the parent comes across the parent/child relationship can be resolved.
If it is persistent or there is a related issue seen these can be investigated further.
