Неадекватное поведение Apache?

Question

[Abrikosik]

Добрый день! Имеется сервер под управлением ubuntu 16.04 со следующей конфигурацией железа: Процессор: AMD A8-6600K, Оперативная память: 8GB, Диски: 2 диска WD Blue 1TB 7200 в RAID1. На данном сервере крутится VestaCP (без nginx, просто web сервер apache) с одним сайтом - небольшим облачком для сотрудников на NextCloud, нагрузка не большая (сотрудников не много), но каждые 2-3 дня сайт падает, а именно сходит с ума процесс apache:

Скриншот

После перезагрузки сервера сайт работает снова 2-3 дня как исправные часы, затем с апачем случается та же история и снова перезагрузка сервера. Остановить процесс apache через панель веста или консоль не выходит. В чем может быть дело?

Дмитрий, robots.txt присутствует и содержит директивы: User-agent: * Disallow: / или боты яндекса могут их игнорировать?

mysql - конфиг в студию

Чутка добавь тут

<VirtualHost 192.168.1.3:80> - у тебя сайт работает в локальной сети ?

memory_limit = 256M повысь до memory_limit = 1024M
max_input_time = 90 повысь до 300
max_file_uploads = 20 до 200

хотя в общем и целом там ничего книмирального нет, хотя памяти 250 это мало, смело можно поднять даже до 2 гб
Есть ли длинные хиты на сайте?
Более подробно о тяжелых хитах настройки сиквела урезаные

А вот этоможет ускорить инодб до 50 раз

innodb_buffer_pool_size = 2048M
innodb_flush_log_at_trx_commit = 2

По сути у тебя захламляется память.

Виктор Таран, спасибо за скорый и развернутый ответ. Сервер весит за маршрутизатором, но из мира доступен - доменное имя, ssl сертификат присутствуют. Сейчас протюню параметры по вашим рекомендациям и буду ждать пару дней - грохнется apache снова или нет. Самое интересное, что он с имеющейся сейчас конфигурацией работал долгое время без падений =)...

Update: Внес изменения, прирост быстродействия наблюдается невооруженным глазом! =)

[Abrikosik]

Виктор Таран, история повторилась, опять apache слетел с катушек... Командой kill убил процесс apache, он сразу же сам запустился по новой и все стало снова работать, е мае каждые два дня его грохать придется!

[Виктор Таран]

Abrikosik, поставь на крон релоад апача в 12 ночи, пока как временное решение, рестарт не нужен тупо релоад.

[Abrikosik]

Виктор Таран, Так и сделал еще вчера, по сути с таким костылем нормально будет... Всем спасибо за предложенные советы и решения!

[Виктор Таран]

Abrikosik, ну это далеко не решение, на лицо утечка памяти

[Vitaly Karasik]

А зачем на сервере бежит VirtualBox?

>После перезагрузки сервера
Вы имеете в виду перезагрузку линукс или апач?
