yum update MemoryError 1 ГБ памяти свободно

Я пытаюсь сделать yum update и получаем "MemoryError". Сервер (коробка OpenVZ) имеет 2 ГБ ОЗУ и сервер Percona MySQL, работающий с настроенным буфером InnoDB 1 ГБ. ОС - CentOS 6.5, ядро ​​2.6.32-openvz-042stab088.4-amd64.

free -m вывод:

             total       used       free     shared    buffers     cached
Mem:          2048        728       1319          0          0         21
-/+ buffers/cache:        706       1341
Swap:         2048          0       2048

На главном компьютере конфигурация памяти коробки:

vzctl set 101 --physpages 0:2G --swappages 0:2G --kmemsize unlimited --privvmpages 2000M:2G --vmguarpages 2000M:2G --oomguarpages 2G --save

Когда я останавливаю MySQL, yum update работает отлично. Зачем MySQL делать yum update потерпеть неудачу, если остается более 1 ГБ ОЗУ?

Полный вывод ошибок:

MemoryError

Аналогичный вопрос Вот но бесполезно, так как у меня намного больше оперативной памяти.
