The module loads fine when you start apache, however, if you try to run httpd -t, apache segfaults. In order to restart apache, you have to run "apachectl stop" then "apachectl startssl". Running "apachectl restart" gives: # apachectl restart /usr/sbin/apachectl restart: configuration broken, ignoring restart /usr/sbin/apachectl restart: (run 'apachectl configtest' for details) # apachectl configtest Syntax OK I don't know if it's related, but if I put php as the first module loaded, apache won't even start. Nothing is logged to the error_log file, or displayed to the screen. apachectl thinks it's running though.
