Hello all, I am facing strange issue in cgi script. Requirement is to upload the file and to print log message in case file size is more than 5 MB. Script is throwing error in case file size is bigger than 5 MB. However it is working fine case if the file size is less than 5 MB. Any suggestions.Pls advice.

use CGI::Carp qw( fatalsToBrowser );
use File::Basename;

use Net::OpenSSH;
use Net::SSH::Expect;
use Data::Dumper;
use Exporter qw(import);
our @EXPORT = qw(copyToTarget);

{
        print ("Content-type: text/html\n\n");
        print <<__HTML__;
