Hi Martin - do you ever figure out the issue here? I am experiencing the same issue, though very rarely (1 time every roughly 3 months) and I am trying to figure out if it is a problem with the server software.

Re: Receiving 0 byte files
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

More failures
Attached is the log from last night's transfers with logging at debug 2. Four files failed, those with filenames ending in 31, 32, 37, & 38.

Re: Zero-length files
Please increase logging level to Debug 2 and post again logs of one successful and one zero transfer.

Zero-length files
The files with zero length were:
The original files did have content on the server.

Re: Receiving 0 byte files
@Berube: Please give us a name of a file that has 0 bytes and a file that was transferred correctly (in the log).

Martin can of course look at the log (I can't as I'm just a guest).
But, if you know that the file on the server is indeed not 0 byte, then it makes sense that WinSCP is creating a file but is unable to get bytes into it. This can be from a connection issue such as with networking equipment. However, if WinSCP creates a file before the server gets into the read file loop, and the server has an issue, WinSCP could in theory leave a 0 byte file around.
I'm not looking at the code or anything.
Session resumption involving session id has nothing to do with this.

Receiving 0 byte files
We have a recurring problem with a script that runs nightly; it works most of the time, but we occasionally get files with no contents. The log from last night is attached; the problem occurred three times last night.
I have noticed something unusual in the logs. When a successful transfer occurs, the log entries contain:
However, when we get a 0 byte file, the "Session ID reused" line is missing:
