This problem appear to be a moving target. I ran the command today and see output below:

I have emailed you the service file as requested.

Well, it is likely occurring on multiple sets of devices, especially if it is the same hardware. Can you get us a copy of those flat files? At least of the one you just showed? You would not happen to be able to correlate if those switches/firewalls were down during the time you ran the check? Or if those ports were administratively down if they actually exist and are not vlans, etc?
