CPanel Web host management software provides an intuitive interface for managing a website server. When running complex scripts on the server, you may occasionally need to stop a process from running to prevent a server crash. You can either stop all processes that a certain user is running, or you can stop a specific process by selecting it from a list of live processes.
Type he server IP address followed by a colon and 2087 or follow your hosting server company or co-location center's directions for accessing CPanel. Enter the administrator user name and password in the text fields when the CPanel login screen appears.
Click System Health on the CPanel WHM home page; if you do not see the icon on your home screen, then locate System Health on the left sidebar menu.
Click Process Manager and wait for the list of processes to appear.
Kill all user processes by selecting the name from the Kill All Processes By User drop-down menu.
Check the list of processes to see which processes might be using an inordinate amount of CPU resources or memory; the percentage of each is listed in the CPU and Memory columns for each process.
Kill any individual processes by clicking the Kill prompt next to its process identification or PID number.
Click the Back prompt that appears after the message "Killed (PID number)" to return to the list of processes. Kill additional processes as necessary.
Test your server to make sure it works correctly. Restart the server if necessary.
