I have CentOS 6 and with webmin/virtualmin panel, and each time that I reboot Apache can't start: Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down I do: netstat -tulpn| grep :80 tcp 0 0 :::80 :::* LISTEN 1584/httpd killall -9 httpd And then Apache can start. But do you why thos problem in each reboot? I like to fix this problem. Thansks you. Ernesto
