Duckdns, mDNSresponder: find resource hogs on Hassio

HI,

My Hassio setup is grinding to a halt now and then, and if not, it is beginning to be very slow.

Have a macbook air which won’t get passed the loading settings at login, my older but stronger Macbook Pro is logging in, but also rather slower than before.

Ive checked my Mac system monitor, and the domain.duckdns.org is eating 40% of my cpu, while mDnsrepsonder is taking 1.4MB Network (all other processes are in the kb range…)

SO my quest is to find whats wrong. How can one debug processes on HAssio?
