The problem is that this line:

if($ipairs{$fk}{$pair}{'pvalue'}){

Rather that just testing if that value exists, it is autovivifying (creating) that value in the nested hashes and setting it to null.

If you change that line to:

if( exists $ipairs{$fk} && exists $ipairs{$fk}{$pair} && exists $ipairs{$fk}{$pair}{'pvalue'} ){

It should prevent the runaway memory growth. As a nice side-effect, your program should run substantially faster also.

BTW. I assume you mean 32GB not 32MB?
