Системное замораживание и предотвращение входа в систему

Welcome to Ubuntu 15.04 (GNU/Linux 3.11.0-12-generic x86_64)

 * Documentation:  https://help.ubuntu.com/

No mail.

Единственным путем я могу восстановиться, должен выключить машину. Я вполне уверен, что диски прекрасны. smartctl не сообщает ни о каких ошибках. Кто-либо видит что-нибудь в файле журнала, который мог быть проблемой?

Question 2

Я наблюдал эту ошибку, которую Вы также отметили выше среди Вашего вывода

4 марта 10:13:08 ядра: [Число] sched: регулировка RT активировалась

После этой ошибки, которую я видел, что использование памяти на сервере увеличило значительно, и это должно все же возвратиться вниз, походит на утечку памяти...

Question 3

Question 4

Это, кажется, экземпляр ошибки в cgroups подсистеме версии 3.11.x ядра Linux ( Отчет об ошибках ), который инициировал мертвую блокировку в ядре, которое приводит к мягкий тупик . Мертвая блокировка происходит, когда процесс пытается очистить cgroup каталог. Я рекомендовал бы Вам обновить свое ядро к более новой версии.

Да, это работало бы:), но помнят .profile, только получен если .bash_profile и .bash_login don' t существуют..., и это - все в удаленной системе, не локальной, конечно — Zanna, 20 August 2016 в 06:36

Старший Фанат зеркально отражает большую часть того, что я сказал выше. Вы, конечно, хотите знать сразу, если Вы находитесь в как типичный пользователь или Корень, и оба из наших ответов объясняют это. Это то, почему я + отмеченный Старший Geek' s отвечают выше. – monkeyman_stones 20 August 2016 в 05:38
