А вот это после передачи файла в почти 5 гиг. Причём в первый раз я
лопухнулся и стал класть его на диск, где было мало свободного места.
Оно якобы со свистом передалось (и я успел раньше времени обрадоваться),
а в конце я получил disk full. Странно. Разве оно так должно было
работать? Второй раз я передал его куда надо, но уже с заеданиями.
Естественно, контрольная сумма не совпала.

Я уж не знаю, что тут странно, а что - нет, но число переданных байт
как-то маловато...

Попробую. Hо придётся ждать подходящего случая. Сервер хоть и глючит
на больших файлах, но всё равно активно используется. Бардак, короче...
