Segmentation Fault Errors

Problem

You see the following error:

Segmentation fault

Cause

This error does not directly relate to the WHMCS software and can occur for many different reasons. It most commonly indicates that PHP is crashing and suggests there is an issue with your PHP installation. For example, this error often occurs because the OPcache PHP extension is enabled and is malfunctioning.

Troubleshooting

Investigate your PHP configuration to find the error. You may want to use the strace utility.

For help, contact your hosting provider or system administrator.

To determine whether the error is due to a problem with the OPcache PHP extension, temporarily disable the extension by adding -d opcache.enable_cli=0 to your system cron command. For example:

/path/to/php -q -d opcache.enable_cli=0 /path/to/whmcs/crons/cron.php

If the error does not occur again after running this command, the problem is the OPcache PHP extension.

For more information and steps to resolve OPcache issues, see OPcache Warnings.

Solution

Make the necessary changes to resolve the issue in your PHP configuration.
