My apache died and I started receiving Unable to open logs! in the error_log. I added ulimit -HSn 40960 to /etc/init.d/httpd which fixed the apache issue. But now my PHP software "ModernBill" is no longer adding clients. It's dying at checkout trying to authorize CC. I think this is a Curl issue. Is there a file limit on PHP that I also need to raise? If I remove a lot of the domains out of httpd.include and restart apache, the checkout process works again. Will I need to recompile PHP? Thanks for the help.
