Добрый день, коллеги.

У моих пользователей локальной сети последнее время постоянно рвется связь pppoe, причем в логах ничего криминального не удается заметить. Вот примеры:

[root@srv enk]# grep 15201 /var/log/messages

Иногда связь держится час, полчаса, а то и четверть часа.

Связь рвется всегда в разное время, причем связь при этом стабильная.

Также в логах часто видны сообщения вида, например, два подряд:

LCP terminated by peer (*Ri*^@<M-Mt^@^@^@^@)

В качестве дистрибутива для BRAS используется CentOS.
