I did not realize this until today. I can certainly add a cron job to email me if named is not running, but is there a more feature-laden monitoring program I should be running to avoid such mishaps? On a somewhat related note: My DNS records are set to expire after 7 days. Why was did it take 14 days before I began to have problems accessing my network by name? I've been working on a theory: My DNS zones are set to expire in 7 days. My nameserver does a zone transfer to my ISP's nameserver, which answers queries for the outside world. I am assuming that my ISP's nameserver answered queries for 7 days, then the records expired. I was still able to access my local network by name for another 7 days because 'fresh' records still existed at one of the outside backup DNS servers. Then, almost exactly 14 days after named dumped core, the records at the backup DNS expired, and I could no longer locate my network.
