What are you doing with your named that is so special that it requires
a modification that no other shop of consequence of which knowledge has
appeared to me has found necessary to implement? Are you running a
single centralized named instead of doing the sane thing which is,
more or less, load balancing with several servers?
I've been with Autodesk (big) and Fujitsu (bigger), and the only name-
server problems I have run into are brand new misconfigurations during
an upgrade (which were pilot error and easily corrected). I've been at
Cypress Semi, and while their named layout made no sense to me, it worked,
and there was no need to seriously tweak the number of open files.
Now either these sites are all lucky as hell, or they planned what they
were doing. Judging by that which you posit, you fall into neither
category (and I'm not attempting to be insulting, here -- not my preferred
mode of operation), which begs the original question of What Are You Doing?
