Instalé un nuevo Ubuntu 12.04 Server + Zend Server CE (MySQL / PHPmyadmin) de deb http://repos.zend.com/zend-server/5.6.0_ubuntu1204/deb server non-free Repository
.
Mi apache2 / access.log se ve así y se mueve cada pocos segundos:

¿Sabes por qué y cómo prevenirlo?
/etc/apache2/apache2.conf
lo he editado/etc/apache2/conf.d/other-vhosts-access-log
porque no encontré "CustomLog" en el primer archivo de configuración. Gracias y espero que ayude
