@stephenw10 said in pfBlockerNG - unbound-control process spikes CPU to 100% every few seconds [SOLVED]:
So just the list containing a bunch of obsolete domains?
Not sure how many domains in that list are obsolete, and if that was the issue, however, what led me to actually remove the list is the fact that there are tons of legit domains in that list that pfBlocker was blocking. If you check the list, you will see asus.com and sony.com in there. And there is absolutely no reason to blacklist those sites. They are legit.
Then I thought this was actually a whitelist that i was using as blacklist, but then you find all those porn sites in there and tons of other entries that are present in legit block lists. Its a mess.
I just removed it and it all works.
