FTP V5R3

Recently our ftp client on our AS400 started putting 3 characters of garbage
into files transferred from an IIS FTP server to a data base file.  The file
does not exist before the FTP starts so it is creating a new flat file in a
temporary library.  This has been working for years.  We recently put on
CUME and Groups.

And have many more loaded ready to install at the next ipl.  Does any one
know of a specific PTF that has broken the FTP client using standard ASCII
=> EBCDIC translation?  The file looks fine from the PC side before the FTP
but is corrupt in the library after the transfer.  Again three bytes of
garbage is inserted before the first record.
