Fails to import certain xml file sizes (LE v2.1 build 1647)

[AlistairH_LBN]

Coreftp LE v2.1 build 1647 fails to transfer xml files of a certain size. With one xml file type, the application falls over when encountering 35kb files; with another xml file type, it seems to transfer 35.840kb of the file (which is generally slightly larger) and then import succeeding files (between one and ten files) in the list as empty shells with no content - and then fall over. I have attempted to reimport the failed files and they alway fail although I can reimport the 0kb files successfully. When incomplete files are imported, they cannot be processed because they contain the xml error message and are incomplete.

I have been using the application interactively as it has failed to import the files consistently when set up as a scheduled task. Doing it interactively has allow me to see that there seems to be a common thread between the files that fail but I have not been able to establish why yet.

Anybody else experienced this and know what the solution is?

Thanks
