If I stop tor then "dig @127.0.0.1 google.com" works 100%. It's seems like the pattern is that when tor traffic builds up so do DNS failures. And then my dig @127.0.0.1 only succeeds about 0.1% of the time. At this stage large amounts these errors start appearing: *> Jan 17 19:27:33 torexit unbound: [559:0] notice: remote address is 192.42.93.30 port 53> Jan 17 19:27:33 torexit unbound: [559:0] notice: sendto failed: Operation not permitted* Quintin On Thu, Jan 18, 2018 at 12:42 PM nusenu <nusenu-li...@riseup.net> wrote: > <tor-admin@portaltodark.world> wrote: > > Resent under the correct alias. > > > > I'm having high amounts of failures on this VPS (PulseServers).
