Why would you want to restart apache? Normally you would never restart apache unless you are adding new websites. So most hosts will not restart apache automatically. keep in mind that a restart will shut down all sites while it is restarting. So having this happen on an hourly basis would not be a good idea unless you are adding new sites every hour.

In that case, look at a "graceful" restart. That will prevent connections from being terminated. Still, hourly is a bad idea.
