kipmi0 cpu 100%

서버의 load average가 1.02 이상 올라가는 상황 발생

조치 후에 load average 0.43 이하로 감소된 것 확인 

문제가 되었던 것은 kipmi0 라는 데몬이 CPU 증가를 야기하였음.

OS 환경 = CentOS release 6.5 (Final) x86_64

증상

  PID USER      PR  NI  VIRT  RES  SHR S %CPU   TIME %MEM    TIME+  COMMAND

해결 방법

참고 URL : http://portal.solutionengineers.net/knowledgebase.php?action=displayarticle&id=6

Seeing 1.00 average server load – 100% of a single core used by kipmi0.  

Resolved by executing from shell, as root –

echo 100 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us

Another note:  

On CentOS/RHEL, that command can be made permanent by adding it to /etc/rc.d/rc.local. The rc.local runs after all of the other init scripts
