1. NETI:ENSURE-DOMAIN-SERVICE-ENTRIES mistakenly tries to update the
INTERNET namespace for uninterned hosts with names like INTERNET|10.2.0.6
If you have an internet namespace, you just get these trash hosts in
your namespace, which is why this bug hadn't been discovered.
If you don't have an internet namespace, the function just blows out.
2. Old world loads that believe in the existence of the INTERNET namespace
do not react in a civilized manner when the namespace server tells them
there isn't an Internet namespace. The just immediately ask the
namespace server about the internet namespace again. Just a couple of
hosts behaving this way can bog down the namespace server with their
continuous requests. We worked around this with a real kludge. In
(flavor:method :server-top-level neti:namespace server) we sleep for
10 seconds every time we get an object-not-found-in-search-list error
for the namespace "INTERNET". This keeps the namespace server from
There's a simple solution for both of these problems. Instead of
deleting the INTERNET namespace completely, just get rid of all the
hosts in it. That's what I did when I built a new world for our
This isn't a solution. It's another workaround. I like my workaround better.
