Thanks for the reply.
Nothing in the system log for this AP, but there is for the counters:
(Aruba-Local1) # show ap debug counters ap-name WA-WAP-01

All of the other AP’s have a count of 0 in the reboots column. This AP is connected back to the controller through a VPN tunnel over an Internet connection. I called our provider and they recorded high signal to noise ratios in the cable modem at the same time that the AP logged those errors in my original post, but interestingly our VPN connection did not go down. Is there a way for me to adjust the keep alive timers for the GRE connection of the AP to the controller, so some other adjustment I can make?
