8.900 Wifi ap disconnects clients and power led flashes

Hi,

Mi Wifi frequently stops working for a short time, since i'm running 8.900 with my AP30.

the only thing that i notice is that some devices get disconnected and that the power led on the AP blinks for a short time, so i think the AP reboots..

the log display's the following:
