When doing a dist-upgrade recently, my lighttpd-1.4.19 install on Ubuntu 8.0.4 has begun failing to restart or reload properly with the /etc/init.d/lighttpd restart command.

~$ sudo /etc/init.d/lighttpd restart
 * Stopping web server lighttpd
   ...done.
 * Starting web server lighttpd
2009-06-13 04:06:36: (network.c.300) can't bind to port:  80 Address already in use 
   ...fail!

The same error occurs when I do a reload.

The way I get around it is to kill lighttpd and then issue the start command, but it seems like I shouldn't have to do that :)

I've looked at my config files, and can't spot any immediate errors. Does anyone have any ideas what can be causing this error? This seems to be the latest version as of writing this question that is available via the apt-get route.

My config file is:

# Debian lighttpd configuration file
