  The message is produced because after the data is written if
  we determine we are at the end of an extent we flush the
  current buffer, close the journal extent (which writes an
  EOF marker) and switches to the next extent. If in flushing
  the new buffer and writing the EOF marker, it cannot fit into
  the last track then MSG4936I is issued.

Problem conclusion

• The end-of-extent marker (JCTEDLDT) is now set to the
  antepenultimate track to make sure that we always switch
  with enough space left on the current extent.
