Log lines indicate the exact moment of the events :
@leonroy said in Unbound was killed: out of swap space:
Jan 11 13:01:33 unbound 63374 [63374:0] notice: Restart of unbound 1.12.0.
and while it's starting - 15 seconds later :
@leonroy said in Unbound was killed: out of swap space:
Jan 11 13:01:48 unbound 63374 [63374:0] info: service stopped (unbound 1.12.0).
and a small instance (< 1 second) :
Jan 11 13:01:48 unbound 63374 [63374:0] notice: Restart of unbound 1.12.0.
To make a long story, go to the Unbound / Resolver settings page and uncheck this :

Stick a post-it on the pfSense box that says :
"Check the resolver logs again after 48 hours and see how many stops/restarts happened the last 48 hours".
If you find "a couple" or even less : issue solved.
