If you look around, you can find documentation on increasing that limit,
but that's well outside the scope of this list. :)

This is a halfway decent outline of what needs to be done:
http://kb.swsoft.com/en/260

However, I wouldn't use pbone or rpmfind. Get the src.rpm packages
directly from your vendor. Also, avoid using "--force" with rpm. Use
"--replacefiles --replacepkgs" instead. Using "--force" may mask other
problems, such as dependencies, that will cause the package not to
function after you install it.

Once you take these steps, you'll be personally responsible for your
updates. You'll need to make absolutely certain that you never patch
your system until you've checked that the updates aren't for packages
that you've rebuilt, and updated those with local version first. It'll
probably be a lot of extra work.

With all of that said, I personally think that the right thing to do is
not to do per-domain log file at all. Instead, use a LogFormat that
includes the virtual host's name, and sort the log files out afterward.
