  FTP client crashes when receiving large files from a z/OS host
  if a secure connection is made using MSCAPI Security. Buffer
  size was too small for the file size being received.
  

Problem conclusion

• PCSFTP.EXE changes have been made to increase the size of buffer
  used to receive large files.
  
  Fix scheduled for Personal Communications 6.0.18 Refresh Pack
  and 12.0.1.0 Refresh Pack.
