Не могу понять в чем дело. маршрутизатор FreeBSD, postfix+amavis+clamav. Все работало, но недавно начались зависания. Выяснилось, что clamav виснет читая свою базу вирусов. Последнее сообщение в логе clamav: Reading databases from /var/db/clamav. Начинаю перезапускать - не помогает. Вырубил freshclam - тоже самое. Удалил базы скачал новые - опять висит. Вот перезапустишь - висит с 15 мин (на том же сообщении) и запашет не на долго.Потом виснет, но не обязательно на "Reading databases from /var/db/clamav", хотя это сообщение последнее в логе в 90% случаях.
В последнее время на сервере ничего не делал.. только bash поставил из портов, заодно установились новые версии каких-то двух библиотек, но ведь старые должны остаться?host#uname -a

В логах postfix и amavis ничего особенного. Когда clamd виснет amavis тщетно пытается использовать clamscan и тоже виснет. Видя все это, postfix говорит, что не может подключится к локальному сокету и откладывает сообщения в долгий ящик.
Буду благодарен за любую помощь.
