We have a small network using Aruba, 1x315, 3x305 that has worked fine for some time but over the last couple of days all the AP's have started to randomly reboot. In the report it says "LAST REBOOT REASON
Preempted by provisioned master"
Power is OK etc. What should I look for?
The firmware is 8.5.0.0_70258 which was updated mid July
Thanks
