I seem to have hit some limit somewhere around 4000 labels in Perl/Tk. I'm using ActivePerl 813 on windows with 2GB of RAM. Here is the code. When I run this, you see the labels start turning yellow and then after that they stop showing up. So it's like I've maxed out and can't make anymore frames or labels? 
#!/bin/perl

use Tk;
use Tk::Checkbutton;
use Tk::Button;
use File::Basename;

### Globals
$version=0.10;
$num_tasks=100;
$max_timeout=60;

################# START OF CODE ##################
my $mw=MainWindow->new;
$mw->title("my app: Version $version");
$mw->Label(-text=>"something\n\n")->pack;

my $mf = $mw->fontCreate('tiny',
   -family=>'arial',
   -size=>int(1));

$main_data_f = $mw->Frame(-background=>'red')->pack(-anchor=>'w');
foreach $i (1..$num_tasks) {
   $main_data_task_f[$i] = $main_data_f->Frame()->pack(-side=>'left');
   foreach $j (1..$max_timeout) {
       #next if ($j>$i);
       if ($j%2) {
          if ($i%2) {
            $test_bg = 'red';
          } else {
            $test_bg = 'blue';
          }
       } else {
          if ($i%2) {
            $test_bg = 'blue';
          } else {
            $test_bg = 'red';
          }
       }
       if ($cnt++>3880) {$test_bg = 'yellow'};
      
       $main_data_time_f[$i][$j] = $main_data_task_f[$i]->Frame()->pac
+k(-side=>'bottom');
       $box[$i][$j] = $main_data_time_f[$i][$j]->Label(-font=>$mf, -ba
+ckground=>$test_bg)->pack();
   }
}

MainLoop;
