без каких-либо заметных изменений на моем сервере (Ubuntu 16.04.1) мой Jenkins перестает работать примерно каждые пару часов. Когда я проверил логи от Jenkins, ничего не связанное. Затем я проверил системный журнал, и есть информация о OOM, вызванном ntpd.
Не могли бы вы помочь мне решить эту проблему?
Заранее спасибо !
