fix high memory usage in cPanel

If you are using web hosting for your blog, business website, or eCommerce site, you might have encountered cPanel. An online Linux-based graphical interface (GUI) is used as a control panel to simplify website and server management.

Managing resource usage, especially memory usage in cPanel, is an important part of its functionality. Overuse can lead to the slowdown of your website and cause problems. So, it is better to stay on top of things.

What is memory usage in cPanel?

Memory usage in cPanel displays the amount of RAM (in Megabytes) the processes in your account are consuming at that moment. Every page, PHP module, script, etc., use a specific amount of memory.

Depending on your hosting plan, the limits for memory usage are given. If you cross the limit of memory usage, your website starts to slow down, affecting the user experience. When such resource overuse happens, you might see an error message.

Some of the common error codes are 508, 500, and 503. Code 508 signifies your entry processes have reached the limit. While codes 500 and 503 signify that the number of processes has reached the limit.

Since the causes and effects of resource usage limits depend on the hosting plan you have chosen, it is better to know some of the common hosting plans.

Hosting Plans

Shared Hosting: As the name suggests, you share the server and its resources with multiple other sites in a shared hosting plan. Since you have to share all your resources like CPU and memory usage, all the other sites have to suffer if one website uses up too much bandwidth. So, many shared hosting servers like Aveshost have CloudLinux OS installed to limit the number of resources each user can consume.

VPSVirtual private server hosting creates a virtual environment that imitates a dedicated server but within the shared hosting environment. Since you get a larger share of the server hardware and its resources, it is less limiting than shared hosting. But you still have limits to the number of resources you can consume.

Dedicated Hosting: In Dedicated hosting, a single server is available solely for your use. Since you have an entire server dedicated to you, the resource usage limits are much higher. Even if you reach the limits, you can always get more bandwidth for an additional price.

The high memory usage in the cPanel problem occurs most commonly in the case of shared hosting plans. While it can happen with other plans, it is less likely as the resource limits are larger.

How to access memory usage in cPanel?

It is important to regularly monitor physical memory usage in cPanel to ensure you do not reach the limit. Although the process might slightly vary depending on your hosting provider, you can still access it in three simple steps.
