      I was using pfsense 2.4.5 and dns resolving was working properly for external host names as well as internal hosts ...
      since I upgraded to 2.5.0 about once a week the unbound resolver stops working (internal hostnames as well as external) ...
      when this happens :
      -top shows the unbound process taking 99% or more of the CPU
      -resolver.log does not seem to contain anything suspicious (log activity stops right at about the time the resolver stopped working)
      -dhcpd.log contains this line right around the time the problem started

      • Apr 3 19:53:19 pfSense dhclient[31512]: Creating resolv.conf

      -restarting the service through the web console does nothing
      -rebooting psfsense fix the issue (resolver works) for about 1 week ...

      • i upgraded to 2.5.1-RC but the issue persists ...

      are there known issues with unbound following a 2.4.5 to 2.5.0 upgrade ?
      are there configuration for the resolver (and dhcp ?) that need to be changed when upgrading to 2.5.0 ?

        @pbr6891 I found similar problem: unbound stopped working once after upgrade from 2.4.5 to 2.5.1. When I restarted unbound all worked again. No resolv.conf in dhcpd.log.

            Same issue here, tried reinstalling because I thought it shat itself during update (again) but it seems it's not just me. I'm running pfsense in kvm if that's relevant to someone
