Cannot transfer a ZIP file to Server

I am using WinSCP version 4.2.7 on a Windows platform. The SFTP server is freeFTPd.
I need to transfer large files around 2GB in size.
I am using scripting/automation.

Here is my .bat file

option batch on
option confirm off
open sftp://xxxxx:xxxxxxx@xxx.xx.xxx.xx:22 -hostkey="xxxxx .."
put %1%

The file that I transfer is C:\FTP_TRANSFER\2.zip

Here is a portion of the logs:

Using username "xxxxxxxxxx".
Authenticating with pre-entered password.
Authenticated.
Starting the session...
Reading remote directory...
Session started.
C:\FTP_TRANSFER\2.zip | 2455527 KiB | 189.2 KiB/s | binary | 100%
Transfer was succesfully finished, but temporary transfer file '2.zip.filepart'
could not be renamed to target file name '2.zip'. If the problem persists, you m
ay try to turn off transfer resume support.
Bad message (badly formatted packet or protocol incompatibility).
Error code: 5
Error message from server: Bad message
Request code: 18
(A)bort, (R)etry, (S)kip, Ski(p) all: Abort

Is it something related to the size of the file?

I do not know, can you upload smaller files? But large enough to trigged the resume support threshold (by default 100 Kb).
