Здравствуйте. Есть сервер, на нем штук 20 openvz контейнеров. Он работает нормально, ram и swap использовано где-то половина.
Вдруг в течение двух часов происходит следующее:
RAM:
s008.radikal.ru/i304/1505/c4/1e8494f75e32.png

SWAP:
s019.radikal.ru/i636/1505/0f/b9921047fc93.png

CPU:
s019.radikal.ru/i602/1505/32/eb6ded3def70.png

Как видите, ram не меняется. swap начинает быстро увеличиваться, а в конце сервер падает.
Вот что я нашел в syslog:
