Доброго времени суток.

Поставил в контейнере:
# rpm -qa | grep apache
apache2-common-2.2.6-alt4
apache2-mod_php5-5.2.2-alt1
apache2-httpd-prefork-2.2.6-alt4
apache2-2.2.6-alt4
alterator-apache2-2.1-alt1
# rpm -qa | grep php
php-base-2.2-alt1
php5-suhosin-0.9.19-alt1
apache2-mod_php5-5.2.2-alt1
php5-libs-5.2.2-alt1
php5-5.2.2-alt1

Всё взято из бранча, как я понимаю... потому не в Sisyphus@

При попытке запустить сервер после останова в ошибках было вот такое:
[crit] (28)No space left on device: Unable to create scoreboard 
(anonymous shared memory failure)
Погуглил и добавил в httpd2.conf такое:
ScoreBoardFile logs/apache_runtime_status

Попробовал старотовать сервер:
[crit] (28)No space left on device: unable to create scoreboard 
"/var/log/httpd2/apache_runtime_status" (name-based shared memory failure)

При этом
# ls -lah /var/log/httpd2/
total 20K
drwxr-x---  2 root apache2 4.0K Nov 10 04:43 .
drwxr-xr-x 14 root root    4.0K Nov  9 00:37 ..
-rw-r--r--  1 root root    2.5K Nov  9 00:51 access_log
-rw-r--r--  1 root root       0 Nov 10 04:43 apache_runtime_status
-rw-r--r--  1 root root    5.2K Nov 10 04:43 error_log

Затем удалил apache2-mod_php5-5.2.2-alt1
Рестартовал - всё ок.

[info] Server built: Sep 28 2007 12:36:18

Поставил mod_php5 обратно, сервер прорелодился.

Теперь пробуем остановить и запустить:

Что теперь делать и кто виноват? ;)

Место-то в контейнере есть?

Внутри контейнера:
# cat /proc/user_beancounters и смотреть на столбец failcnt для shmpages.

После чего уже в HS:
# vzctl set <VID-контейнера> --shmpages 16384:16384 --save

и пытаться запустить апач еще раз.

Вообще, в случае OVZ, /proc/user_beancounters -- это первое, куда надо
заглядывать в поисках проблем (failcnt - показатель).

Действительно:
resource           held    maxheld    barrier      limit             failcnt
shmpages              0       8192       8192       8192          8

  failcnt
shmpages           8208       8208      16384      16384          8

Т.е. мы просто увеличили предел?
