too many open files.

Hi, My script is attempting to make a copy of a file (httpd.conf) open the copy. look for a string using ereg() and if it finds it. Open the actual httpd.conf and replace it (The string) with somehting else. However when I try to run the script I get "Too many open files" I was wondering if there was a limit, it seems so I can't have to files open at the same time? Can I change this or of course is there a better sugestion?
