When an attempt to gracefully stop the Apache HTTP Server fails, the agent for Apache HTTP Server kills all the processes similar to the following pattern:
Apache HTTP Server 2.0
/usr/sbin/httpd -f \ /etc/apache2/httpd.conf -k start
IBM HTTP Server
/opt/IBM/HTTPServer/bin/httpd -f \ /opt/IBM/HTTPServer/conf/httpd.conf -k start
