Я создал весеннее загрузочное приложение, которое использует базу данных postgresql с hibernate. Соединение с базой данных в порядке, вставка строк работает некоторое время правильно. Есть метод, который вставляет много строк в цикл for, он тоже кажется хорошим, но через некоторое время я получаю следующее сообщение об ошибке:
