[Nut-upsuser] "Master privileges unavailable" &

[Huge]

What does this mean?

>Feb 19 07:58:11 apophis upsmon[533]: [ID 702911 daemon.alert] Master privileges unavailable on UPS [ups at apophis]
>Feb 19 07:58:11 apophis upsmon[533]: [ID 702911 daemon.alert] Reason: Access denied

And is it normal for my UPS (APC SmartUPS 620) to drop into battery mode for a few seconds every day
or so? Or is this a main supply glitch? Nothing else in the house notices anything.

Thanks,
