Total Physical Memory: 32,689 MB Available Physical Memory: 23,282 MB The code that does not work is another code written elsewhere(again perl), but it is time consuming to get that working And i am unable to shorten the template file to get to a stage where it will be working. Thanks for all the help though. Really appreciate.

Note that your 32-bit Perl can, on Windows, at most address 4GB of memory. Most likely it can only address 2GB of memory.

Upgrading to 5.28 (or a more recent version of Perl) from http://strawberryperl.com/ will allow you to address more memory if you install a 64bit version.

Sounds like 32bit Perl on 64 bit Windows then?

You could try the trick outlined in this node: Memory usage in Perl on Windows systems to get 3GB available for Perl instead of 2GB. It's a workaround, but might help you until the data and/or template get bigger.
