Unbound occasionally crashing
-
I'm running pfSense 2.3.2, unbound will sometimes crash after my OpenVPN client acquires a new IP address. I've checked the systemlogs & unbound logs and I can't see what maybe causing this to happen…
-
I believe this maybe the error that could be causing it?
php-fpm 93864 /rc.newwanip: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1', the output was '[1470845134] unbound[23702:0] error: bind: address already in use [1470845134] unbound[23702:0] fatal error: could not open ports -
Do you run the Service Watchdog package by any chance?
That error looks like a race condition where something tried to trigger Unbound to launch but it was already running, hence the 2nd instance could not bind to port 53 and failed to start. Probably a harmless error and not indicative of a crash. There are probably a lot of race conditions like this still in pfSense. My very uninformed understanding is that some of that will be improved for the 3.x releases (still a long way off) which aim to eliminate PHP. I could be quite wrong about this.

If you have pfBlockerNG installed and have DNSBL enabled. That will be causing it. Its not a package issue but pfSense.

I do have PfBlockerNG installed however DNSBL is disabled. Also I'm not using service watchdog.
