www/lighttpd 1.4.45 broken mod_fastcgi for PHP

[Miroslav Lachman]

Hi,
I upgraded from 1.4.44 to 1.4.45_1 and after service restart I got tons 
of following error in error.log:

2017-03-01 00:32:56: (mod_fastcgi.c.3565) pid  59896 1 not found: No 
child processes

I have this in lighttpd.conf and it was working for years

fastcgi.server = ( ".php" =>
    (( "socket" => "/tmp/php-fastcgi.socket",
       "bin-path" => "/usr/local/bin/php-cgi",
       "bin-environment" => (
          "PHP_FCGI_CHILDREN" => "4",
          "PHP_FCGI_MAX_REQUESTS" => "4000" ),
       "bin-copy-environment" => (
          "PATH", "SHELL", "USER" ),
       "allow-x-send-file" => "enable"
    ))
)

I don't know what the error means and how to solve it. I searched the 
web but found nothing relating to this.

This is on FreeBSD 10.3 amd64 with freshly build packages in our 
Poudriere (ports OpenSSL used as default)

Am I alone with this error?
