Since it sounds like the file xfer was started and going, the ftp client
you are using could open large files (in fact, all binaries that come with
2.6 onwards should have large file support)... so it is most probably your
FTP daemon whose write()s to the new file on the receiving server are
failing, because the file in question has reached the 2GB mark.

I would suggest recompiling your own proftpd, and when you do a 'make',
see if the "-D_LARGEFILE_SOURCE -D__FILE_OFFSET_BITS=64" are included in
the compiler command. If they're not, edit the Makefile and add those
flags to the CFLAGS line. 'make clean' and then attempt 'make' again.

And that is a default mount option since 2.6.
