Ways of resolving resource overusage issues

What is resource overusage and why would you see an error message

All Shared Hosting plans have resource limits set by CloudLinux LVE (Lightweight Virtual Environment) - resources include CPU, physical memory, entry processes and number of processes.

If your account starts hitting resource limits regularly, this is resource overuse, and you will either see an error message or your website will work slower.

3 codes you are likely to see are 508, 500 or 503.

- Code 508: means your entry processes have reached the limit
- Code 500/503: means a number of processes have reached the limit

If the limit has been reached by one of the domains, all other domain names hosted in the account will be affected as they share the same resources.

Below are steps to find, and resolve resource overuse.

Step 1: How to check your usage and limit
Step 2: How to define which processes are impacting usage limits
Step 3: Troubleshooting


Step 1: How to check your usage and limit

Log in to your cPanel account to view your current usage under the Statistics section:



For a description of each of the listed resource limits, please refer to this article.

Step 2: How to define which processes are impacting usage limits

If it happens that some resource limits have been reached in your hosting account, the first thing to do is to understand which processes are impacting usage limits.

If issues last for more than a few minutes, it is possible to check active running processes in the account at the time of overuse. We have a separate guide that will be helpful for you with a description of what active processes are, how they can be defined and killed.

In case of any questions or if our assistance is needed, do not hesitate to contact our Hosting Support team via Live Chat or email.

If the issues last for a few seconds, we won’t be able to check and define which active processes have caused it as this information isn't saved in such a short time. We recommend you look at the resource usage over a specific time from the Resource Usage menu in cPanel. This may give you an indication of what resources are reaching their limits.

A handy guide on the "Resource Usage" menu functional can be found here.

Troubleshooting

Once you have identified which process are impacting your limit, here are the most common ways to reduce the resource usage:

Recent site updates: If this is the first time you have had resource usage issues check the latest updates you’ve made to your site. Recent changes may be impacting your usage levels.

New plugins/themes: If you have installed a new plugin or a theme, try disabling it and monitor the impact on your account's performance for at least 10 minutes.

NOTE: Changes will not take effect immediately. You will need to monitor website performance for about an hour.

Increases in site traffic: Go to the Awstats menu in cPanel. It will provide information about visitors to your site and will help you to understand if there has been a recent spike in number of visits. If you do notice a growing number of visitors, and are still having resource outages, we recommend you to review your current hosting plan and consider its upgrade.

Optimize your websites (you can use Google PageSpeed Insight for diagnosing). If you are a WordPress user, this article may come in handy.
