<p>PHP is only guaranteed to work with the Apache2 "Prefork MPM"
(Multi-Processing-Module) and you need to have apache2-prefork installed. This also
means that the APACHE_MPM in /etc/sysconfig/apache2 must NOT be set to "worker". You can

Documentation : Thread Safety</a></code> For general information about MPMs please see
