Looking for this interface?
Note:

Your hosting provider can enable or disable this interface for resellers in WHM's Edit Reseller Nameservers and Privileges interface (WHM >> Home >> Resellers >> Edit Reseller Nameservers and Privileges).

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:

  1. Select Enabled under RLimitMEM Settings.

  2. Enter a value in the text box.

    Note:
    The RLimitMEM value must be an integer greater than 1.

  3. 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)).
