While you method should work without the seeming memory leak problem it
might be interesting to further isolate the problem by trying this:
  
  put fld "log" into tLogData
  delete last line of tLogData
  put txt & return before
  put tLogData  into fld "log"

Also, is the value of tx appended or overwritten in each iteration?
