Apache fails when restarting through WHM or automatically

Whenever I try to restart Apache by clicking the link in WHM or when I add a new domain pointer/parked domain or when cPanel attempts an automatic restart, apache fails and all sites go down. The only way I can get it to go back up is by typing the path to apachectl then startssl. Can someone tell me how to fix it and get it back to normal? I have to go out of town for a week and won't be near a computer much so if the server goes down the sites will be down for a while.
