Проблема! Сервер примерно раз в сутки(иногда чаще)перестает отвечать - не работают сайты, не зайти по ssh. При этом сам сервер пингуется. Проблема точно не с железом. Свап на сервере почти не используется (несколько килобайт)
В messages ничего нет. В логах http-errors:

Что с этим делать? Перерыл гугль - ничего толком не нашел. Возможно, кто-то специально вешает сервер? Помогите советом плз!
