If a provisioner has any DNE errors at all, it logs the job as an error. It does not show any number for unresolvable count. You don't know what the issue is without looking at the provisioner View Errors, or in the job message, which doesn't show any error other than the DNE that the user has to assume is the cause of the error.

Jobs should distinguish between stacktrace level errors, versus a successful run that just had some subject problems.
