That makes sense.  We make use of the options in resolv.conf to allow us 
to reboot the DNS servers without causing any interruptions.

For Dirk though, this isn't so much a Nagios or monitoring issue as it 
is a general *nix one.  The real question here is why the DNS servers 
become unavailable so frequently.
