Пауза убивает активные закачки

[MonkAlex]

Если во время закачки поставить на паузу, а потом возобновить, то помирают соединения с базой. Це странно, ибо используется Async контекст, т.е. на паузу должен реагировать корректно.

Возможно дело в том, что using криво работает с async-await конструкциями и соединение с БД может быть реально завершено к моменту снятия с паузы.

В целом, критичность низкая, повторное выполнение обновления скачает всё, в базе ничего не должно запороть.
