ST hub DNS bursts


#1

Hi!

Last night my internet connection went offline. From that moment on my ST hub (v1) tried to resolv pool.ntp.org constantly. I usually have around 2 DNS requests per second in my network. Now it went up to 400 requests per second. I checked with tcpdump and the majority of the questions has been the pool.ntp.org question from ST.
It seems the hub ended up in an endless loop. That is really stupid and a good way to DDos yourself.

Any ideas what might cause such behaviour?
