Hello
I've just installed cPanel/WHM
and just created an account and i did nothing else
So, i noticed the server RAM Usage is high since my server has 2GB Ram,
and i've run top command and Java was taking 39% of the ram - screenshot attached

and attached another screenshot of the process with high memory usage

and since i'm only will use the server as mail server, do i need java and perl ?
if not, then how to disable them?

Thanks.

Good day, MotazHakim!

Perl is required in order for cPanel to run, but you are free to remove Java if you do not plan on using Tomcat or Solr.

You can uninstall Java with the following command, but be sure to uninstall Tomcat and/or Solr if they are installed first:
Code:
yum remove java-headless
