Добрый день! Я тут новичок просьба не ругаться. у меня такая беда, временами зависает cyrus, и письма пользователи отослать не могут, висит до перезапуска cyrus'a, после работает нормально какое то время. Куда копать подскажите?! Может что то с бд cyrus'a?

Linux 2.6.32-5-686 i686 GNU/Linux Postfix version 2.7.1 Сyrus 2.2

такая ошибка connect to /var/run/cyrus/socket/lmtp Connection refused часть лога.
