I just did an experiment in the interpreter which
corresponds to this script:

    import ftplib

    of = open("large_file", "wb")

    def callback(data):
        of.write(data)

    ftp = ftplib.FTP("localhost", userid, passwd)
    ftp.retrbinary("RETR large_file", callback)

    of.close()
    ftp.close()

The file is 2 GB in size and is fully transferred, without
blocking or an error message. The status message from the
server is '226-File successfully transferred\n226 31.760
seconds (measured here), 64.48 Mbytes per second', so this
looks ok, too.

I think your problem is related to the FTP server or its
configuration.

Have you been able to reproduce the problem?
