Question : Cron to kill processes on Centos server

I want to create a cron to kill porcesses that have been running for a long time on my centos server.
For example If I find a mysqld process running for a long time I manually type killall mysqld and that fixes the high load on my server.
I want a cron that checks that , is that posible ?
What would be the line that I should add on my crontab ?

Thanks

Answer : Cron to kill processes on Centos server

You can use top and awk to extract data to billed the list of PIDS to be killed.

Instead of concentrating on killing processes, you should fine tune the system to avoid this issue.
i.e. if you have a mysql server, limit simultaneous connections to 10 instead of unlimited. Configure the mysql server based on the available resources.
Similarly for the web server and php, limit the resources to lets say 5 or 10 child web servers. Limit the php to 5 or 10 as well.  This way you can have your system running in an optimal shape with the limited resources that are available.
With these adjustments, there should not be a need to 'kill' processes that run too long.
