1) Where can I download the kernel so I can look through some of the

2) More description of NPROC, MAXUSERS, and "scales", and UNIX03 would
be helpful. I'd be happy to read up on them if someone could point me
in the right direction. Where should I look? The source code?
That's the best place, or Amit Singh's "Mac OS X Internals" book.
You can also learn much from reading other books on the design of UNIX, like
"The Design and Implementation of the 4.4 BSD Operating System" or "UNIX Internals."
3) Does anyone know what buttons I could push at Apple to get (at
least) the server kernel compiled with "larger scale" or something
like that? I'd like this fix to be available to the larger community,
which really means getting it into an official OS update.
No idea, but is your mail server really so busy that there are THAT many
simultaneous users, or is there something else going on?
Have you verified that the process limit is, indeed, being hit?
