What are the advantages of djbdns? We were looking at putting a caching
nameserver on each fetcher node to reduce load on a single dns server.

What we were seeing is the dns server cached the addresses in memory
(bind 9x..) and because we were caching so many addresses on a single
dns server it would eat up memory and eventually begin swapping to
disk. When this occurred the server load got up to 1.5 and the
iowait was near 100%. Basically it stalled the box. Requests were
still getting through but it was very slow. Our solution (at least
temporarily was to restart the bind service (not the box just the
daemon) every couple of hours to flush the memory.
Switch to djbdns?
