Lighttpd

i installed lighttpd a couple days ago and while the server is running i am getting a lot of errors in the logs.

i've attached a snip of what my logs look like.

i have in my config:

server.event-handler = "linux-rtsig" # (linux 2.4.x)

fastcgi.server = ( ".php" => ((
"bin-path" => "/usr/local/bin/php",
"socket" => "/tmp/php-fastcgi.socket",
"max-procs" => 1,
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "16",
"PHP_FCGI_MAX_REQUESTS" => "10000"
),
"bin-copy-environment" => (
"PATH", "SHELL", "USER"
),
"broken-scriptfilename" => "enable"
)))
