Перестали регистрироваться транки

Доброго времени суток! Вчера, без каких либо действий с моей стороны, отвалились все транки с Астера. Ребут сервера не помог. Астер пускается, но транки не зарегистрированы. В Trixbox начала тупить функция сохранения конфигурации через перезагрузку.(Менял провайдера) "Перезагрузка" через Trixbox происходила минут 20. После команды reload в CLI астер ребутнулся и транки зарегистрировались. После этого сервер тушили на ночь. Утром все запустилось как нужно, астер поднялся, транки зарегистрировались - все работает. Однако то, что произошло мне не внушает доверия. Просмотрев логи, Я нашел следующие ошибки:
