Привет, я несколько дней запускаю сервер Proxmox, на котором работает около 10 виртуальных машин. Всё шло хорошо, пока вчера не запустился бэкап (в режиме snapshot). Мне кажется, что у сервера закончилась память, и он убил 3 работающие ВМ. Это было бы нормально, если бы памяти не хватало, но у меня 32 Гб ОЗУ, из которых используется только 15 Гб для работающих ВМ. Возможно, я не совсем правильно понимаю журнал ошибок, и мне было бы интересно узнать, что ты думаешь по этому поводу. Спасибо и sorry за очень длинный лог-файл...
