Spring Batch предоставляет все байты для записи не были успешно записаны ошибка

Question

Я написал весеннее пакетное задание, которое использует flatFileItemWriter для записи огромного количества данных в файл.Работа периодически прерывается со следующей ошибкой org.springframework.batch.support.transaction.FlushFailedException: Could not write to output buffer.Я заглянул в исходный код и обнаружил, что он конкретно терпит неудачу в в этом месте , что означает, что bytesWritten не равен байту, который он прочитал.Кто-нибудь здесь знает, почему он терпит неудачу на этом этапе.Спасибо.

Вот полный след ошибки стека:
