Server Load 4.17 and swap 100%

While checking the CPanel interface I noticed the values of the subject and was wondering if I should worry or not.
My server is a Linode VPS with 8GB of RAM and 4 cores of dedicated CPU.

Swap is virtual memory (using the disk as RAM). In general, you never want web servers to swap. You will need to identify what is actually using the RAM.

To assist in your efforts, you may want to install the Munin plugin in WHM. This can provide some more detailed metrics.

In my experience, these services often consume a lot of RAM:
- PHP-FPM or PHP FastCGI processes
- MySQL
- Apache connections not exiting (stuck in waiting (W) in the apache status page).
