Apache2 server didn't start after reboot

[PlymWS]

I rebooted my server and got this error when trying to restart the Apache2 server (which didn't automatically restart)

0: /opt/psa/admin/plib/common_func.php3:175
psaerror(string 'Unable to make action: Unable to manage service by websrvmng: websrvmng: Service apache2 failed to start')
1: /opt/psa/admin/htdocs/server/restart_services.php:30

Any ideas ?
