Hi Monks,

I'm trying to perform a very simple file copy on Linux and have run into what appears to be a possible file size copy limitation. Whenever I copy small files in my script less than 1 GB, it appears to work fine. However, I need to copy some very very large files greater than 4GB. When I run this simple script it appears that it works as I get no errors but the file never copies. Does anyone have any insights or meditations to offer? Thanks. Here is my simple script that I am running: 
use File::Copy;
use strict;

copy("ers-as1.dsk","ers-as2.dsk");

[download]
The ers-as1.dsk file is 5.2 GB and when I check on this script after 45 min. no file has been copied. When I perform a "cp" at command line I can get the file to copy. I'm running Linux Redhat 2.1, (actually ESX server 1.5.2)
