Hey guys, being a relative beginner to perl this might be an easy one for most of you, but here we go: I'm using Algorithm::SVMLight to classify some very large input (billions of lines). The problem is that memory usage is steadily growing, although it should not be.

Here's a snippet: 
my $svm = new Algorithm::SVMLight;
$svm->read_model($myconfig->{'model_file'});
while (<>) {
   $svm_res = $svm->predict_i(\@indices, \@values);
}

Basically memory usage keeps on going up with each call of the predict_i subroutine. Obviously I have other things in my loop, but If I comment it this subroutine, there's no increase in memory usage, so it has to be the source of the problem. Can I prevent this problem without actually changing the subroutine itself? Any help or comment is much appreciated.
