Hi, I use monit to monitor apache2 and it works fine. But sometimes, after change web settings, restart performed by ISPConfig is detected by monit and monit restart apache2 too. Than ISPConfig revert configuration change with error: Code: WARNING - Apache did not restart after the configuration change for website domain.ltd. Reverting the configuration. Saved non-working config as /etc/apache2/sites-available/domain.ltd.vhost.err WARNING - Reason for Apache restart failure: Restarting web server: apache2AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/000-ispconfig.conf:69 (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down AH00015: Unable to open logs Action 'start' failed. The Apache error log may have more information. failed! What is the best way to prevent this colision?
