This guide details resource exhaustion errors that can occur when managing and visiting a website.

Preamble

• Resource limits are in place to maintain the integrity, stability, and performance of the shared server, while ensuring a fair experience for all users.
• If a website or application requires significantly higher resources, it may be necessary to switch to a Serveur Cloud or another type of virtual hosting where resources are allocated more flexibly.

Error origins

Fatal error: Maximum execution time of 30 seconds exceeded

This error occurs when the server sets a time limit for script execution, usually to avoid tasks that take too long. For example, if a script attempts to resize many large images in a single operation, it may exceed the allowed execution time limit. The server imposes this limit to ensure a quick response to user requests. The path often mentioned in the error can indicate a more precise origin (for example Fatal error: Maximum execution time of 30 seconds exceeded in /home/www/1234567abc/web/wp-includes/media.php on line 123)

memory limit exceeded

This error occurs when the script or application uses more memory than allocated. This can happen when a script processes a large volume of data or when there is a memory leak. For example, an image management script may consume more memory than allowed, resulting in this error.

Resolution paths

Some ways to resolve these errors:

• Check the scripts that make multiple connections to the server to display data.
• Optimize the script(s) in question so that they require fewer resources.
• Increase the limits of the concerned site to allow the script to complete its tasks and/or limit the number of simultaneous connections (especially on a Serveur Cloud where the limits (RAM, execution time, simultaneous connections) can be significantly increased).
• Migrate your hosting to Serveur Cloud.
