You have probably already done that, but I'd first suggest you be
certain that named is actually using more than 1000 sockets (use lsof
or something like that).

If that's the case, I recommend you switch to a beta.  Even if you can
avoid 'the too many open files' error, you won't be satisfied with the
overhead of the non-scalable API with such a large number of sockets.
