WHM's Resource Limits feature allows you to allocate available system resources to cPanel users. It could be beneficial in preventing some accounts from abusing server resources.
Aside from the resource restrictions set by a package, you can alter the limits for a cPanel account specifically. This can be accomplished in the following manner:
1. In the WHM select the Modify an Account option from the drop-down menu.
2. In the Account Selection area, select the account for which you want to change the limitations and click the Modify button.
3. You'll be taken to the account adjustment window, where you can alter specific resource limits in the Resource Limits section.
