This is associated with "nscd", a name-service-cache daemon. Basically,
because NIS is so inefficient, Sun implemented a caching daemon, which
you can tune. The communication channel to the nscd uses a new kernel
construct, known as a "door". This new communication method is not
documented properly, and in fact, is documented as an experimental
interface that Sun may opt to discard at some later date.
However, I do suggest that you look at the /etc/nscd.conf file. We
found that it is grossly misconfigured in its default state, especially
with respect to name lookups when you are running DNS...
I hope this helps...
