Есть ли способ определить Размер виртуальной памяти процесса в момент его уничтожения с помощью linux oom-killer.
Я не могу найти какой-либо параметр в файле /var/log/messages, который может сообщить мне общий размер виртуальной машины убиваемого процесса. В /var/log/messages имеется много другой информации, но не общий объем VM процесса.
Это машина centos 5.7 x64.
Ниже приведены содержимое /var/log/messages:
