Modify Apache Memory Usage Limit
WebHost Manager includes a function that automatically calculates the memory limit needed by Apache and resets the memory used by Apache to that amount. This frees up your memory for other operations, and is useful on busy or full servers.
1 To access the Security Menu, click on Security, on the main screen of your WebHost Manager interface.
2 Click on Modify Apache Memory Usage Limit.
3 The modified memory usage results will now be displayed.
