[sisyphus] kernel 2.6 & memory leak

[Ilia Menchikh]

Доброе время суток.

Сори что сюда, хотя речь об Мастере 2.4.

Обнаружилось сразу 2 проблемы:
 
1. Утечка памяти в md5sum
2. Зависание по этой причине ядра 2.6

coreutils-5.2.1-alt5
kernel-image-std26-up-2.6.8-alt9

последние сообщения ядра перед умиранием:

По free подобное происходит как только кончается оперативка и начинает 
использоватся своп.

Конфигурация машины:

Кто-нибудь может подтвердить?
Как лечить?
