In the 5.7 ECO3 releazase notes it says :

4.21.60 Data appears to be truncated on the remote end

    Problem:
    The SFTP and SCP utilities are not properly 'put'ing fixed
    record format files to non-VMS systems. The data appears to
    be truncated on the remote end.

    Solution:
    This problem is corrected in this release.

But I guess you have checked all rellevant relnotes, right?
