Strange.  Does hanging up the process do the same thing as ndc -s
reload?  Traditionally, I've always "kill -1 <pid>" for bind 8 (I don't
know why - just what I'm used to, I guess).

What platform is this?  Is it a GENERIC kernel, or has it been tweaked?

If you can experiment, does removing any files from named.conf help?  512
sounds like the limit on per-process open files, but I'd have to double
check that.  It sounds like when ndc is trying to connect, bind can't
allocate another file handle to deal with the socket... reducing the
number of files in named.conf _may_ reduce the file handle count
and allow ndc to function properly... this is a blind guess, though, and
may be of no use... YMMV!

Does the initial run of bind load and run okay indefinitely?  Or does
what's up always tell you dns is down after 20 minutes (i.e. even after a
reboot)?

Not on that one, sorry.
