Scope: Prime Mover Free / Pro version


This error means your server has insufficient timeout setting to complete the process. Prime Mover usually states at which specific method the error occurs. So please take note when reporting or fixing this specific error. It could be the method that handles the database dump, copying media directory, etc.

When this error occurs, Prime Mover executes shutdown procedure, terminates the process and cleans the temporary directory of any unfinished files or folders to prevent clogging your server.

There are several ways of fixing this error for which this tutorial shows.

PHP-fpm timeout configuration steps

The following steps works for PHP 7.0+ PHP-FPM in Ubuntu 16.04 + / Apache server . This requires root access to your server. Ideally you can get this with VPS or dedicated hosting.

  • Know your specific PHP version. You can get this via WordPress admin -> Tools -> Site Health -> Info -> Server .
  • Login to your SSH using root shell.
  • Go to this path: /etc/php/PHP_VERSION/fpm/pool.d , replace PHP_VERSION with your PHP verson. For example if you are using PHP 7.3.8, then its a PHP 7.3 version. So the path will be /etc/php/7.3/fpm/pool.d
  • Open the file www.conf
  • Look for request_terminate_timeout

By default request_terminate_timeout is disabled. So it will look like this (starts with semi-colon).

;request_terminate_timeout = 0

If you don’t have semi-colon that starts with that request_terminate_timeout then it means its currently using that timeout setting for your PHP processes.

To disable it, make sure you add semi-colon before it. For example say, a 60 seconds timeout is currently imposed in your PHP process:

request_terminate_timeout = 60

You can disable that by adding a semi-colon:

;request_terminate_timeout = 60

However if you only want to set a very high timeout setting, add the value say for example 1 hour timeout.

request_terminate_timeout = 3600

  • Restart PHP-fpm and Apache. This is the command to use:

sudo service php7.3-fpm reload;sudo service apache2 restart;

That assumes your PHP version is 7.3, just like illustrated in the above example. Replace php7.3-fpm with your actual PHP version (e.g. php7.0-fpm)

Changes needed on php.ini

Ideally none, since Prime Mover already adjust the runtime PHP timeout by using set_time_limit() and max_execution_time.

You can adjust memory_limit which is desirable to set it as high as possible to avoid getting any memory errors. However Prime Mover will attempt to increase memory settings during runtime just like WordPress does.

Apache timeout configuration steps

  • Go to /etc/apache2/
  • Find the file apache2.conf
  • Look for Timeout directive, by default this is set 30 0r 60 seconds. You will need to set this to a very high value , the same that you have set in PHP request_terminate_timeout

Note, in some configuration; this is added in httpd.conf. Please refer to this documentation in details.

If you are using any timeout related Apache module, you may need to disable or adjust them accordingly also. For example

Nginx timeout configuration steps

There are already several good tutorials on the Internet on setting Nginx timeout. Please read the following selected posts:
