I have a server running lighttpd with fastcgi, and it appears to be working correctly.

However when I try to upload a file using a form, I get a 500 Internal server error, along with the following in the logs:

2012-03-23 18:25:09: (mod_fastcgi.c.2566) unexpected end-of-file (perhaps the fastcgi process died): pid: 2755 socket: unix:/tmp/php-fastcgi-1.socket-0
2012-03-23 18:25:09: (mod_fastcgi.c.3354) response not received, request sent: 50437 on socket: unix:/tmp/php-fastcgi-1.socket-0 for /index.php?url=brand/manager, closing connection 

I've been looking around for a long while now trying to find a solution to the issue, but nothing I'm trying is working. My current fastcgi conf looks as follows:

server.modules += ( "mod_fastcgi" )

fastcgi.server = ( ".php" =>
               ((
                   "socket" => "/tmp/php-fastcgi-1.socket",
                   "bin-path" => "/usr/bin/php-cgi",
                   "allow-x-send-file"     => "enable",
                   "max-procs" => 1,
                   "broken-scriptfilename" => "enable"
                ))
             )

If anyone could suggest if there is anything wrong in the configuration it would be greatly appreciated, or any suggestion as to what I might do? As I say, it is only happening when trying to upload a file (the file in question being only 45k).

Thanks,

Dan
