I have came across an interesting issue today, I tought to share it with in case it would save someone some time. Apache suddenly stopped working, I started receiving email from ChkServd with the following: Code: httpd failed @ Mon Aug 27 08:16:51 2012. A restart was attempted automagically. Service Check Method: [socket connect] Reason: Unable to connect to port 80 on 127.0.0.1: Connection refused: Died at /usr/local/cpanel/Cpanel/TailWatch/ChkServd.pm line 577. Number of Restart Attempts: 6 Startup Log: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:443 no listening sockets available, shutting down Unable to open logs Running the following commands shows that there is nothing listening on port 443: Code: lsof -i :443 netstat -an | grep 443 After looking deeper I found that apache was just updated, and mysteriously the entry was added to httpd.conf, this conflicts with the same entry in ssl.conf. Removing one of the entries fixed the problem.
