Сервер VPS, перезапускающий MOD_SECURITY?

Мой сервер VPS капризничал в последнее время, например, в прошлые выходные модуль PHP, Imagemagick просто прекратил работать и я должен был сделать, удаление PERC / переустанавливает.

Сегодня мой сервер был полностью безразличен в течение максимум 20 минут. Это - программное обеспечение в жестком реальном времени, и время простоя полностью недопустимо. Вот журналы до завершения работы. Я был бы очень признателен за любой совет, мы связались с нашим хостом, но в конечном счете это падает на мои плечи, чтобы понять и зафиксировать. Я в конечном счете просто надеюсь добраться до следующего шага своего понимания этой проблемы!
