I can't seem to find any documents for this strange error that i'm getting.
A few of our locations had this issue over the weekend where all the AP's dropped for a few hours, and in the logs I get the following.

Now i'm assuming that the AP's lost connection to the controller, but unsure what could have caused that... We're utilizing our 3850 switches as our controllers and then Cisco Prime Infrastructure to manage all the controllers. The switches at the locations that had this issue didn't lose power and were all working on Friday when I left at end of business day.
