This guide explains how to increase the max_children value on Managed Cloud Server to increase the number of simultaneous PHP processes that can be used by your site. This will be very useful for resolving infinite page loading issues on your site.

Preamble

• By default on all hosting, the max_children limit is set to 20.
  • Although it is possible to increase this value from the Infomaniak Manager, the max_children limit is automatically adjusted based on the configuration of your Managed Cloud Server.
  • To increase this limit on shared hosting, migrate to Managed Cloud Server.
• To understand how to calculate the max_children needed as accurately as possible, refer to this article on the subject.

Increase the max_children value

Prerequisites

• Ensure that you have the necessary resources on the Managed Cloud Server.
• Ensure that all resources of the Managed Cloud Server are not being used; if it turns out that they are fully used, increasing the max_children value will have no effect (Modify Managed Cloud Server resources).
• Monitor the resources of your server, in case the resources of your server are reached, it will be necessary to check the optimization of processes and your site before considering increasing the max_children value.
• Consult the PHP error reports from the /ik-logs folder (master process php logs - file name: php-fpm.log) to check if the "max_children" limit has been exceeded... example of error: [05-Jul-2024 09:08:58] WARNING: [pool www.infomaniak.ch] server reached max_children setting (20), consider raising it
