php won't start! (It has been fine, though)

Hello, I restarted my httpd server, and now I can't get php to start with it. Although it says 'starting httpd', and I get no errors, there are no httpd processes shoing in my process list. Here is the output from gdb: (no debugging symbols found)... (gdb) run -X -f /etc/httpd/conf/httpd.conf Starting program: /usr/sbin/httpd -X -f /etc/httpd/conf/httpd.conf Cannot access memory at address 0x4035d0d0.
