How to kill a cron job that's hanging around

If like me, you have your magento on a server, you might find that you're constantly nagged by "excessive resouce usage: " messages from lfd/csf firewall.

Or you may just notice that cron jobs aren't finishing.

To kill them you need two things
1) SSH access under the same user as the cron job is running (usually just your cpanel username)
2) the process ID (PID)

Then it's simple

$ Kill -9 PID

All done.

Course, you shouldnt kill active processes. Kill -9 is very harsh, and can cause problems if the cron job was actually half way through doing something. Better to wait maybe a day or so before killing processes!
