Getting errors on new lighttpd installation gw_backend.c.324) child exited: 0 unix:/var/run/lighttpd/php.socket-0

The log includes the following two lines repeatedly. It seems to handle html just fine except I need to be able to run php on a regular basis. :

(gw_backend.c.324) child exited: 0 unix:/var/run/lighttpd/php.socket-0

Here is the lighttpd.conf file:

conf-enabled contains:

ls conf-enabled/
10-fastcgi.conf  90-javascript-alias.conf

Whereas 10-fastcgi.conf is:

cat conf-enabled/10-fastcgi.conf 
# /usr/share/doc/lighttpd/fastcgi.txt.gz
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ConfigurationOptions#mod_fastcgi-fastcgi

server.modules += ( "mod_fastcgi" )

I think that's all. Let me know if there is something I've overlooked. The socket is owned by www-data,

ls -l /var/run/lighttpd/php.socket-0

srwxr-xr-x 1 www-data www-data 0 Nov 1 13:36 /var/run/lighttpd/php.socket-0

And running the app with -D from the command line didn't produce any errors.

sudo lighttpd -D -f /etc/lighttpd/lighttpd.conf

Thanks, Jim.
