There was already a similar for for permission denied spammed when the
network was down. But your system returns a different errno in that
situation. I have squelched the errno EADDRNOTAVAIL (Cannot assign
requested address): it is hidden when verbosity is low, visible if you
increase the verbosity. That hopefully keeps Philippe's logs clean.
Thanks! That only partially addresses the problem, though: while
unbound will no longer clutter logs as long as the network is down, it
will still eat CPU -- and it will do so silently now, unless verbose
logs are enabled.
It seems to me that it would be better if Unbound did not busy-wait
for the network to come back up, or for a change in whatever condition
is causing the spew. However, I don't know the code well enough to
suggest any particular changes to accomplish this.
