Cron - restart apache

[werwin01]

I need some help creating a cron that will restart apache every hour.

*/60 * * * * root service httpd restart

If I put that in /etc/crontab would it restart apache every 60 minutes?

It should, although why do you want to restart apache every hour?

Also is would be better to use this

* */1 * * *

Well, probably not every hour.

There are times when apache loads get very high, and start to eat up the CPU and cause high server loads. I don't know what causes this, but restarting apache always works to stop the problem. Maybe restarting it every day, or if possible, is server loads reach a certain level, then restarting apache?

There is a domain monitoring tool in the 3rd party forums which will collect cpu usage stats for all domains, maybe its one of your users scripts?

Only way I can think of at the moment to restart if apache server load goes over a set limit is to setup the cron to run a php or perl script every minute or so which would get and parse the server load and then decide whether or not to restart apache. Although I suggest looking for users scripts that could possible be causing this with that domain monitoring tool.

I'm running one a gnutella web cache, which might be the problem.

14938 blacknex 21 0 0 0 0 Z 4.7 0.0 0:00 0 perlgcache.cgi <defunct>

The CPU is just 4.7 for it though, and it's not running under the actual apache process name, and the problem occurs under the apache name.

Thanks for your help.
