FreeBSD 4.10 and Apache 2.0.5x: setting limits

[Sander Holthaus - Orange XL]

You can set the limits (ulimit) for Apache 2 through a variable
(apache2limits_args enabled by apache2limits_enable) in rc.conf. If enabled,
it uses, by default, the limits for login-class daemon as found in
/etc/login.class;
 
daemon:\
       :coredumpsize@:\
       :coredumpsize-cur=0:\
       :datasize=infinity:\
       :datasize-cur@:\
       :maxproc=512:\
       :maxproc-cur@:\
       :memoryuse-cur=64M:\
       :memorylocked-cur=64M:\
       :openfiles=1024:\
       :openfiles-cur@:\
       :stacksize=16M:\
       :stacksize-cur@:\
       :tc=default:

 
I take it these settings are quite general, and may not be sufficient (to
restrictive or not). So I was wondering what kind of limits other users are
using. And how those settings scale or depend on various configurations?
 
Googling, or Apache: Definitive Reference / Apache Cookbook do not seem to
provide any clues here :-(
 
Kind Regards,
