Unfortunately it was inconsistent all the time. Morning, noon or night it
failed. In my setup I had it forwarding to my internal DNS servers. I  would
do a ping mypc and get a response. Twenty seconds later I would ping the
same computer and get unknown host. It really should cache for more than 20
seconds. Sometimes I would get a response, sometimes I wouldn't, and my
internal DNS servers have not gone down. I finally ran Ethereal on my DNS
servers and found that they were not getting all the request from dnscache.
Again, sometimes it got a request and other times it didn't. I changed to
dnsmasq and have not gotten any more complaints.

Hope this helps,
