Почему clamav может падать (freebsd)?, !*! billymicrosoft.ru, 08-Июн-05, 06:32  [смотреть все]
Стоит связка postfix(2.1.5,1)+clamav+clamsmtpd(1.1), система freebsd 4.10
Никакие рары не прикручены, в свойствах кламава указано проверять архивы.
Примерно раз в три/четыре месяца кламав вываливается с ошибкой:

Первый раз это произошло на версии clamav-0.80_3, последний раз произошло на версии clamav-0.85.1, железо сервера проверенное, система стоит без перезагрузки 160 дней.

        Что толку то все обновлять (к тому же кламав последний)?
        Проблема вылазит только у кламава, причем как в версии 0,80 так и в 0,85,1.
        И точно выявить ее очень трудно, т.к проявляется раз в несколько месяцев.

        Может ли это быть связано с архивированными аттачами?

      Тоже вот начинаю думать написать скрипт который по крону раз в час бы смотрел запушен ли кламав и если нет то перестартовывал его.
