I'm semi-new to Perl, I haven't used it in years. I'm trying to write a basic script to transfer large amounts of data from a windows 7 machine to a linux server. Below is a brief portion of my code (some bits removed but I don't believe they are related to my issues). After much searching, I decided to go with SFTP->FOREIGN with the BACKEND into SSH2. Large in part, everything works great. All of my testing worked liked a charm. However, these tests used small amounts of data (~50MB). My script is set to run nightly at midnight and transfer any new folders on windows to linux. Each folder could be up to 20GB or more. Right now, there are 6 or 7 folders waiting to transfer. I've run it several times and most of the files are transferred, but never all. It'll go through the first folder and copy ~70% - different each time and crash before it has a chance to get the next folder. I can't get any error codes or debug information. No matter what I try, a new cmd windows pops up with an error and it crashes and closes automatically before I can even see it. Getting very frustrating. It looks like I may have to write my own recursion and use the regular 'put' instead of 'rput'. Any ideas?

    use Net::SFTP::Foreign;

    use File::Path;
    use Cwd;

    use strict;
    use warnings;



        if (opendir(DIR, $SOURCE2)){
            while (defined ($file = readdir(DIR))) {
                if (($file eq ".") || ($file eq "..")){
                }

                elsif (-d "$SOURCE2/$file"){
                    if (-e "$SOURCE2/$file/Transferred to $HOST.txt"){
                        if (int(-M "$SOURCE2/$file/Transferred to $HOS
+T.txt") > $life) {
                            rmtree ("$SOURCE2/$file");
                        }
                    }
                    elsif (-e "$SOURCE2/$file/RTAComplete.txt") {
                        if (($sftp->rput("$SOURCE2/$file", "$PATH/$fil

                            open FH, ">$SOURCE2/$file/Transferred to $
+HOST.txt";
                            print FH "";
                            close FH;
                        }
                    }

            }
            closedir(DIR);
