Starting apache fails (could not bind to address 0.0.0.0:80)

Update: Already fixed, it seems that one of VirtualHosts configurations files was wrong in sites-enabled. I have Ubuntu 11.10 When I run the command to start apache2: ``` sudo /etc/init.d/apache2 start ``` I get the following error message: Starting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. I run this command in order to get the process that is using the port 80: ``` sudo netstat -ltnp | grep ':80' ``` Which returns this output: ``` tcp6 0 0 :::80 :::* LISTEN 1176/ ``` To know which process is I run this command: ``` ps -wlp1176 ``` That returns: ``` F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 5 D 33 1176 1 0 80 0 - 0 exit ? 00:00:00 apache2 ``` But if I try to kill the process: ``` sudo kill -9 1176 ``` It doesn't kill it, if I run again the netstat command still appears listening and apache start fails. Any suggestions?
