How to Set Memory Usage Restrictions in Cpanel
Valid for versions 82 through the latest version
Overview
This interface calculates and sets a new memory limit for Apache processes. This limit only applies to each individual Apache process. For more information, read Apache’s RLimitMEM documentation.
Note:
A process memory limit increases the stability of your server but may reduce process performance.
Set a memory usage limit
To set a new limit for Apache processes, perform the following steps:
- Select Enabled under RLimitMEM Settings.
- Enter a value in the text box.
Note:The RLimitMEM value must be an integer greater than 1.
- Click Save.
Restart Apache
After you set a new memory limit, you must restart Apache in order for the change to take effect.
- To rebuild and restart Apache now, click Rebuild Configuration and Restart Apache.
- To rebuild and restart Apache later, use WHM’s HTTP Server (Apache) interface (WHM >> Home >> Restart Services >> HTTP Server (Apache)).
