Ошибка записи на swap-устройстве, Результат: hostbyte = DID_BAD_TARGET driverbyte = DRIVER_OK

Мой корневой сервер в 1 и 1 не отвечал на HTTP и SSH, поэтому я вошел в последовательную консоль. Он залил мое соединение бесконечными сообщениями об ошибках, как указано ниже.

Я инициировал перезагрузку, и теперь все работает правильно.

После поиска в Google я установил smartctl и провел короткое самотестирование, которое показало, что устройство исправно.

Вероятно ли это, что скоро произойдет сбой диска или это просто какая-то программа? Я предполагаю, что устройство подкачки также может заполниться, когда огромные объемы памяти будут потреблены ошибочной программой? Как я могу узнать наверняка?

Сервер уже не отвечал неделю назад, когда я только что перезапустил его без должного расследования.

Сервер работает на CentOS.
