Unbound restarts when host joins network
-
I've been trying to troubleshoot an issue where Unbound seems to restart itself whenever I bring my laptop (wireless) device online. Usually the sequence of events on the DNS log is a few dozen DNS requests (from my laptop) and then this;

This is a very common occurrence and sometimes take up to a minute for me to resolve anything as it restarts a few times. This only seems to happen when I open my laptop up. Anyone have any insight?

@bhjitsense said in Unbound restarts when host joins network:

Yep.
When a new DHCP lease comes in, and you have checked "DHCP Registration" :
then the Resolver (unbound) gets restarted.
Solution :
Define a static lease for your portable - this way it will always obtain the same IP, and .... the Resolver will know about it upfront, and doesn't get restart any more.
The "Static DHCP" should be checked.
