[Sysadmins] ntop умирает

[JaMm]

Здравствуйте.
Установил на шлюз (altlinux 4.0.1) ntop-3.3-alt2.
Подправил конфиг, создал пароль на admin. Всё работает http сервер (ntop'а)
выдаёт статистику, НО спустя некоторое время, 1-2 часа, процесс умирает не
оставляя никаких записесей в логах.
Привожу последние строки из лога:

Как видно - никаких аномалий, ошибок нет.
И ещё после старта по команде service ntop status выдаёт ntop is dead, but
subsystem is locked
Хотя
# ps -e|grep ntop
899 ? 00:00:05 ntop
таким образом он работает ещё часа 2 потом вырубается.
Что скажите?
спасибо.
