now for the FixedCycleDataRecorder the size always plus 1 it's just for handling unfinished kdata and it would be treated as finished when only got duplicated record in not realtime mode.

from your trace,it seems some exception happen and start from the first entity again.

The problem is that we could not confirm whether the previois fetched entity finished yet, it need to run twice to check,so ...

just ignore the exeption point and continue to the next is another solution, I could provide this option.
