Linode Alert - скорость входящего трафика

Использование ЦП линода

Как я могу исправить это? Это Centos 6.7, и я использую top и htop, но когда я использую эти инструменты, сервер работает нормально.

И сервер начинает сходить с ума и потребляет много оперативной памяти, посмотрите это:

HTOP линода

Можете ли вы помочь мне, ребята? у кого-то есть такая же проблема или что-нибудь? заранее спасибо.
