Seems you have to supply the attrs parameter to make do_mkdir happy. Also it returns 0 as a successful return, so "or die ..." will do the wrong thing unfortunately. Your code with a few modifications works okay:

use strict;
use warnings;
use Net::SFTP;
use Net::SFTP::Attributes;

sub sub1
{
    my @InboundParameters = @_;
    my $num = $InboundParameters[0];
    print "started thread $num : Establishing connection with $Inbound
+Parameters[1]\n";
    my $host = $InboundParameters[2];
    my $sftp = Net::SFTP->new($host, user => $InboundParameters[3], pa
+ssword => $InboundParameters[4], debug => 0)
                    or return ( { 'errors' => "Unable to connect to $h
+ost: " . $@, 'success' => 0 } );
    my $attrs = Net::SFTP::Attributes->new(());
    $sftp->do_mkdir("ftp2SAT5", $attrs) and die;
    print "done with thread $num\n";
    return $num;
}

sub1 qw(1 me localhost my_username my_password);
