Thank you for your reply.

The first part of the code is at the highest level of the program, so @input is used throughout the while loop, which basically is the whole program. The first part just opens a file with website-addresses which get loaded into @input and then the loop cycles through them.

In any case, I have now changed the code to the following: 

use warnings;
use strict;
use diagnostics;
use HTML::FormatText;
use HTML::TreeBuilder 5 - weak;
open INPUT, "< D:/websitelocations.txt" or die "Problem: $!";
my @INPUT=<INPUT>;
close INPUT;
while (@INPUT) {
 my $input=shift(@INPUT);   
 chomp $input;
 print $input;
 my $content=HTML::FormatText->format_file($input, leftmargin => 0, ri
+ghtmargin => 50);
 # followed by regular expressions, the results of which are saved pri
+nted into a new file, all of this is currently disabled
 }

The memory leak is still there though. It runs out of memory after about 3000 files, but I have more than 28 000.

I still think it has something to do with HTML::FormatText. I read elsewhere that this calls HTML::Treebuilder which in the past has caused memory leaks when the object was not explicitly deleted. I added now

use HTML::TreeBuilder 5 - weak;

which should take care of it according to CPAN documentation on HTML::TreeBuilder. However, apparently it does not. I also tried to add explicit calls to the delete function:

$content->delete(new)

As well as

$input->delete(new)

But this just gives me an error message: can't locate object message
