WinSCP fails to transfer a 32 GB file

Using WinSCP 4.2.7 on server 2003. I also reverted back to WinSCP 4.1.9 and receive same results.
I am trying to copy a 32 GB file from a VMS server. I am using SFTP to transfer the file. I waited 30 minutes to see if it would eventually initiate the transfer, but no such luck. I am able to copy files up to 3.5 GB without any issues.
Here is the log file. I truncated the end, since it ran for 30 minutes, but it was just 30 more lines of "Session Upkeep".
Any ideas or thoughts.

Re: WinSCP fails to transfer a 32 GB file

Sorry, no idea. Do you have any logging form server side?
