How to solve this issue and why it happened?

Answer 1

Well after try and rerun the code change i did to solve the issue is making the batch smaller ---> from

%10 to %5

but did not know why it happened if some one knows please improve my answer. the code became "working version"

if (++count_cursor % 5 == 0) {
      session.flush();
      session.clear();
  }
