fast cgi process Core Dumps Light goes 100% cpu

[anonymous]

Major things in the Lighty conf:

server.modules        = ( "mod_status","mod_fastcgi","mod_accesslog" )
fastcgi.debug = 1
fastcgi.server = (
    "/" =>
      ((  
          "socket"   => "/tmp/dump.fcgi.socket",
          "bin-path" => "/tmp/core.pl",
          "bin-environment" => (
                          "PERL5LIB" => "/home/dmarkham/stable2/evdb/modules/",
                               ),
          "check-local" => "disable",
          "disable-time" => 1,
          "max-procs"   =>  1,
      ))
)

the Perl script

#!/usr/bin/perl

use CGI::Fast qw(:standard);

This technique works just fine in 1.4.13..

[Olaf van der Spek]

How about 1.4.18?

This might be fixed due to http://trac.lighttpd.net/trac/ticket/1245

[dmarkham@…]

yes! in 1.4.18 it looks good...

Thats a lot I'll start the migration.
