Apache restart failed. Unable to load pid from pid file and no httpd process found in process list.
If apache restart reported success but it failed soon after, it may be caused by oddities with mod_ssl.
You should run /scripts/ssl_crt_status as part of your troubleshooting process. Pass it --help for more details.
Also be sure to examine apache's variouse log files.
