      Hi Everyone,

      I've been noticing insane load averages periodically on my box. After trying to look into logs and activity etc, I am noticing that whenever the filter reloads (say after updating PfBLockerNG or enabling/disabling actual firewall rules for the interfaces) I have a LOT of filterDNS processes going. See the paste below.
      Does anyone have any suggestions on where to begin diagnosing this particular issue? I tried a reinstall to see if it made a difference but seems not.
      I need to try keeping this on 2.3.2 as I only encountered this issue when updating 2.3.2 to 2.3.2_p1, so i'm not sure if something changed on this update? new bug?
