Tried another test, and set the server IP to 0.0.0.0 in bb-hosts, and it all

It seems to resolve using nslookup on CLI, but not in bbtest.net
Eventually added the --no-ares option, and all is good in our again.
Are you using a local DNS resolver, or a remote one ? Xymon tends to
hit DNS servers pretty hard when starting all the network tests, so
I strongly recommend using a local DNS cache.
It could be a bug in the C-ARES library, of course.
