There are 2 limits on open files.  One is a system wide limit and the 
2nd is a per process limit.  The per process limit should be 20 not 15.

Well I just checked and on my Mandrake 8.2 it's 16.  Look in 
/usr/include/bits/stdio_lim.h.

Check to see if the kernel uses this include to define the max or 
another local (linux src) include file.  You should be able to change 
this to fit a larger size.  I'm surprised Apache doesn't have checks to 
deal with this issue.
