CPU : 2개RAM : 64G
OS: CentOS 5.4
로 서버를 운영하고 있습니다.
허나 RAM 3G 도 사용하지 않고서 장비가 다운되는 현상이 발생합니다.
이것저것 찾아보고 있는데 궁금한 점이
kernel-PAE 라는 것이 고용량 RAM을 사용할 수 있게 해준다는 글을 봤는데요
CPU 정보를 들어가서 PAE가 있는지 확인하라고 하더라구요.
cat /proc/cpuinfo
로 확인하면 아래와 같이 PAE가 있는것을 확인할 수 있습니다.
그런데
lshw 로 확인하면 cpu2 와 같이 pae가 없는 cpu도 있더라구요..
왜 장비 이력에 차이가 발생하는지 궁금하구요.
장비가 지금 64G 를 효율적으로 사용하지 못하고 있는데요. 해결책을 알려주세요.ㅠ
