Hi all,

I am trying to fork a daemon process off whenever a user logs into my web application. I am currently trying to do it using a system call to call a script that does the actual forking, but it doesn't seem to be working. I also can't figure out how to get more visibility into the problem. All I know is when I do a test-login, Dancer seems to go through everything fine, but all I get from the system call is 256. Here's the code from the web app:

sub start_client_handler                                
{
    my ($user_no) = @_;                                               
+                                          
    my $cmd = '/usr/bin/perl'                                         
+                           
            . ' /home/username/workspace/Space/bin/start_client_handle
+r_daemon.pl'               
            . " $user_no"                                             
+                           
            . $ENV{IS_TEST} ? ' test' : '';                           
+                           
                    
    system($cmd);
}

And here's the code that is supposed to fork the daemon. When I call it by itself (not from my Dancer web app), it seems to work fine. Not sure what's going wrong when I call it from the app...

#!/usr/bin/perl
use strict;
use warnings;

use AnyEvent;
use Proc::Daemon;
use Space::Handler;

my $user_no = shift @ARGV;
my $base_dir = '/home/username/workspace/Space';

die "Error: user_no must be provided to the client handler." unless $u
+ser_no;

$ENV{IS_TEST} = !! grep { lc($_) eq 'test' } @ARGV;
$| = 1 if $ENV{IS_TEST};

my $daemon = Proc::Daemon->new(
    work_dir     => "$base_dir/bin",
    child_STDOUT => "$base_dir/logs/client_handler_$user_no.log",
    child_STDERR => "+>>$base_dir/logs/errors/client_handler_$user_no.
+log",
);
$daemon->Init();

my $handler = Space::Handler->new(
    user_no  => $user_no,
    daemon   => $daemon,
);
$handler->run();

my $keep_alive = AnyEvent->condvar;
$keep_alive->wait;

Any guidance/direction would be much appreciated!
