查看因OOM被kill掉的进程记录 grep -i 'killed process' /var/log/messagesdmesg | egrep -i 'killed process'
As I understand, the size of the virtual memory that a process uses is listed as "total-vm". Part of it is really mapped into the RAM itself (allocated and used). This is "RSS". Part of the RSS is allocated in real memory blocks (other than mapped into a file or device). This is anonymous memory ("anon-rss") and there is also RSS memory blocks that are mapped into devices and files ("file-rss”).
