Lighttpd

Are each of those entries supposed to be associated with ".php"? If so, you appear to have extra parenthesis in the subsequent php-* configs. Try this:

fastcgi.server = (
  ".php" =>
  ( 
    "php-local"     => ( ... ),
    "php-tcp"       => ( ... ),
    "php-num-procs" => ( ... ),
  ),
)

Parenthesis is exactly set like you mentioned in the example config as in my own config. My configuration was working flawlessly in 1.4.46.

I didn't see it at first either, but you have different parenthesis, yours look like this:

fastcgi.server = (
  ".php" =>
  ( 
    "php-local"     => ( ... ),
  ),
  ( 
    "php-tcp"       => ( ... ),
  ),
  ( 
    "php-num-procs" => ( ... ),
  ),
)

I.e. the last two blocks don't have a (extension) key in the array.

Thanks for the enlightment. Now I see it. If i try to remove the parenthesis I just get parser errors.

Forgive us for not trusting you, but could you maybe paste your new config? :)
It is possible though that the parser doesn't accept newlines in all places.

Sure, no problem, I reverted it, but I did it again this is actual state:

You still need one set of parenthesis around the three blocks; you removed them all.

I tested it and can confirm that it works if parenthesis are set as advised. The default fastcgi.conf delivered in the tar.gz should be looked over. The pasted config runs on 1.4.46 also without problems. Im happy, Thank you!

If someone read that in the future:

fastcgi.server = ( ".php" =>
                  (
                    "php-local" =>
                     (
                       "socket" => "/tmp/php-fastcgi-1.socket",
                       "bin-path" => "/usr/bin/php-cgi",
                       "max-procs" => 1,
                       "broken-scriptfilename" => "enable",
                     ),
                    "php-tcp" =>
                     (
                       "host" => "127.0.0.1",
                       "port" => 9999,
                       "check-local" => "disable",
                       "broken-scriptfilename" => "enable",
                     ),
                    "php-num-procs" =>
                     (
                       "socket" => "/tmp/php-fastcgi-2.socket",
                       "bin-path" => "/usr/bin/php-cgi",
                       "bin-environment" => (
                         "PHP_FCGI_CHILDREN" => "16",
                         "PHP_FCGI_MAX_REQUESTS" => "10000",
                       ),
                       "max-procs" => 5,
                       "broken-scriptfilename" => "enable",
                     ),
                  )
                )

Thanks @thnow . I have updated doc/config/conf.d/fastcgi.conf in the source tree (and will push it to lighttpd git master soon)

While the config may have been "accepted" at lighttpd startup in prior versions, it might not have been behaving during runtime as you would have expected. The stricter config checking now rejects the incorrect, and possibly misleading, syntax.
