Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• C-FTP xfer of data between UNIX and MVS(SERVER) in FILETYPE=JES
  - in the middle of a data xfer (txt) a lot of XTRA x'40' are
    added.
  - data is shifted which makes the JES job unreadable.
  - when the C-FTP trace is turned on the client/server
    interaction is ok.
  - error is detected in the JES SNAP trace.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of MVS TCP/IP V3R1 C-FTP server.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: C-FTP transfer of data between UNIX     *
  *                      workstation and MVS server using        *
  *                      FILETYPE=JES results in extra x'40's.   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When a JCL file is moved from UNIX to MVS via C-FTP and using
  FILETYPE=JES, the file contents are shifted.  The problem
  occurs intermittently and not at all when the C-FTP trace is
  active or if the FILETYPE=SEQ. The extra blanks (x'40's) are
  added to the front of the record as well as anywhere in the
  record; where the blanks occur is random.
  

Problem conclusion

• This is a timing related problem in module EZAFTSMJ.  The logic
  had an exposure that resulted in the symptoms reported. The
  change was made to JesWrtStream to gather any tiny buffers into
  a large buffer to contain at least one entire record, 254 bytes,
  during binary data transfer.
