How to use the Background Process Killer in WHM

The Background Process Killer requires that you have root access before you can use it.

The Web Host Manager (WHM) has a number of ways that you can manage the health of your hosting server. The Background Process Killer option provided in the System Health section of the WHM allow yous to take action if there is a specific process that could leave your server vulnerable to attack. This article will describe the use of the Background Process Killer. Stopping the processes is important as they can often lead to denial-of-service attacks. If necessary, you can also create trusted users that can run these processes.
