Hi

Is there any script or software that can restart httpd,mysql,exim or named if

The server load goes beyond a certain limit
These services go offline


To be specific on condition 1, I am looking for a script/software that can take mysql down for some seconds until the server load becomes low.

There is now software available which does the following task, but you can always write a custom sript. That won't be difficult.

I am looking for free version,or some referral to the tutorials. I am not thinking to pay.

This could be done with Nagios Event Handlers

Beat me to it! We used to use this but we've moved to an in house system to do local server monitoring. It did the job at the time though and was very simple to setup. Although I don't think it'll stop the services but it'll restart failed and email on high load and such.
