hostapd: ubus inteface crashes hostapd?

[Nick]

Is someone massively utilizing the ubus interface from hostapd? I'm 
doing this with dawn and I saw that blocktrron already fixed some 
infinity loop. However, currently DAWN is crashing the hostapd. I make 
extensive use of the get_clients, all subscriptions, disassoc_immidient 
calls.

Of course I don't want to exclude that the error is on my side. I just 
wanted to ask if someone is doing something similar. It is just weird 
for me that dawn can crash hostapd since it is only connecting via ubus 
and uses iwinfo library to get signal strength and channel utilization 
from wifi interfaces.
