    I'm on a linode 6 core 8GB RAM VPS running WHM 11.48.2 (build 3) running on CentOS 5.11 all packages are up to date.

    Using their Longview analytics, I can see that cprsvd-ssl is constantly at 50% - 70% CPU as seen in the attached image.

    I found a thread from 2008 that a recent cPanel update caused this issue and I'm curious if it's happened again? This started happening after I did a cpanel update myself.

    Just a follow up to this, I found the dormant setting inside tweak settings panel. I've enabled it for cprsvd-ssl to see if that helps.

    My next step is to research disabling cPanel from listening over ports I do not use.

    For reference, here's my sar -q output:

    enabling the dormant setting has helped tremendously.

    Hello,

    I am happy to see this helped. Note that you are referring to the "Dormant services" option under the "Software" tab in "WHM >> Tweak Settings" for those not familiar with this option.

    Thank you.
