The message "Act like CageFS is disabled" is displayed in the "/var/log/messages".
Starting from CageFS v.7.2.0-1, you can prevent a process from working if it can't enter CageFS. The option is disabled by default.
To enable it, run the following commands:
touch /etc/cagefs/fail.on.error cagefsctl --remount-all (cagefsctl --remount <user>)
To disable it, run the following commands:
rm -f /etc/cagefs/fail.on.error cagefsctl --remount-all (cagefsctl --remount <user>)
The message “Act like CageFS is disabled” in the
/var/log/messages will be displayed regardless the
/etc/cagefs/fail.on.error file is available or not.
Explanation using PHP Selector as an example:
The reason for the problem was that when the CageFS is down, for example during a remount, the request that comes to the webserver can't enter CageFS and apply PHP Selector settings so it creates a PHP process that uses the default settings. This process can stay alive for a long time, as long as there are calls to the server. The request coming to a webserver is unable to enter CageFS and apply PHP Selector settings like PHP version and extensions.
