Not able to put files on SFTP server

Hi,

I have written a small perl script which executes following command line to put the encrypted backup on SFTP server.

$cmd = "WinSCP.com /log=\"$winscplogfile\" /command \"option batch abort\" \"option confirm off\" \"open ".$FTPUser."\@".$remoteHost."\" \"cd $remotePath\" \"mkdir $destDir\" \"cd $destDir\" \"bin\" \"put \"$archPath\"\" \"bye\"";

(I am passing the password (input) to this command using stdin.)

The files I transfer are of type .tar.gz.enc or .tar.gz
It works some times. But recently, when tried on my new machine Windows XP. & FTPShell Server running on Windows 7.
I am getting following error -

. 2012-10-26 13:59:09.136 File: backup_2012.10.26_13.58.15.1.tar.gz.enc"

I am not able to figure out issue.
help is appreciated.

How to diagnose the exact error here? is it related to data blocking or some kind of blocking on windows system?

Please attach a complete log file.

Hi,

Thanks for reply.
I have attached logs.
This log is for following operations -
1. a test to check whether the remote location on remote host exists or not.
2. actual transfer of backup to remote location.
