Using setsid and exit I got extra httpd daemon at each fork.

So it doesn' seem a good solution

If I use Core::exit(0) instead of exit I got an httpd daemon in zombie state.

    $pid = fork();
    if( $pid == 0 )
    {
        setsid();
        # -----------------------------------------
        close STDIN;
        close STDOUT;
        close STDERR;
        # -----------------------------------------
        my $p_pid;
          $p_pid = getppid;
        ae_util::mylog( "START Child process: $$.$p_pid " );
        sleep 1;
        ae_util::mylog( "EXIT Child process: $$.$p_pid " );
        # CORE::exit(0);
         exit;
    }

I found another solution which is more simple and seems to works well:

$SIG{CHLD} = 'IGNORE';

and

    $pid = fork();
    if( $pid == 0 )
    {
        # -----------------------------------------
        close STDIN;
        close STDOUT;
        close STDERR;
        # -----------------------------------------
        my $p_pid;
        $p_pid = getppid;
        ae_util::mylog( "START Child process: $$.$p_pid " );
        sleep 1;
        ae_util::mylog( "EXIT Child process: $$.$p_pid " );
         CORE::exit(0);
    }

Do you known if that solution ( ignore SIGCHLD signal ) have some drawback ?
