Это холодный старт тора, когда ещё никакой статистики нет. Адекватны ли сообщения о том, что

No current certificate known for authority xxx; launching request.

или это свидетельствует о какой-то паталогии? Ранее пользовался только версией 1.x, недавно перешёл на 2.x, так что опыта нет. Повторные запуски уже идут без подобных предупреждений. Насколько я слышал, то ключи DA уже встроены в тор, а тут получается что он их как бы запрашивает... или встроены лишь "базовые", а текущие он запрашивает? Там вроде бы еженедельно то ли продляются ключи, то ли меняются, для DA. Просветите пожалуйста, что происходит.
зы: версия 0.2.0.30, ручная связка tor+privoxy.
