Apache Memory Usage Restrictions in WHM

This function will calculate your apache memory usage based on your memory usage history and set a new memory limit for Apache processes. Limiting each process’ access to memory will increase the stability of your server but may reduce performance slightly. This is a limit for each Apache process, not for all Apache processes combined.

Proxy access for cPanel/WHM/webmail.

With Linux Shared Hosting accounts, you have access to a control panel that contains the admin functions of your account. Generally you would access this using the following syntax:

This URL causes a problems for some owners, as it attempts to connect to port 2082. This is an uncommon port and may be blocked by corporate and public firewalls, thus preventing access.

If you are unable to access your cPanel using the above URL, you can access it using the following syntax:

This syntax does not connect using an uncommon port, and will allow you access. The same rules apply for Webmail and WHM.

Note: You will need to create A records for each subdomain above if not created by default during account creation process.
