So far, dnsfwd has shut down with two different errors, IF it has answered dns queries:

dnsfwd --bind-udp 127.0.0.1:9999 --connect-tcp 127.0.0.1:53
<2>shutdown: Socket is not connected

dnsfwd --bind-udp 127.0.0.1:9999 --connect-tcp 127.0.0.1:53 --logformat human --loglevel 5
CRIT: shutdown: Socket is not connected

It had managed to stay up for hours, when no query was thrown at it.

When the connection attempt to the upstream DNS server fails, the process dies with:

<2>connect: Connection refused

Getting the following during make on macOS (OS X / Darwin):

/dnsfwd/src/dnsfwd.hpp:137:7: warning: suggest braces around initialization of subobject [-Wmissing-braces]

Supposedly, SO_DOMAIN is Linux only and SO_PROTOCOL is not defined on OS X and platform-dependent:

I realize this is prototype project written on Linux. It would be nice to be able to built and use it on non-Linux BSD-like platforms such OS X, since the project is the implementation of a great concept.
