I have this problem also if I test with the following configurations:
Second test set

• SSHD Release May
• Client JSCH 1.5.3
• Connection type (User / Password and PK)
• Client OS: Windows 7 - 64 bits
• Server OS: Windows Server 2008 r2

Third test set

• SSHD Release April
• Client WinSCP (Both with and without RESUME)
• Connection type (User / Password)
• Client OS: Windows 7 - 64 bits
• Server OS: Windows Server 2008 r2

Fourth test set

• SSHD Release May
• Client WinSCP (Both with and without RESUME)
• Connection type (User / Password)
• Client OS: Windows 7 - 64 bits
• Server OS: Windows Server 2008 r2

The file sent is a text file generated on the Server and trying to get it from the client. And only works if I use the sft.exe client provide in the build, any other client looks that it fails. And I think is something in the server side when reading the file.

Some more tests I have done, Any file over 127kb will fail (the limit is between 69 KB and 127 KB. Is consistent the problem with winscp and JSCH Jcraft java libraries.
