解决linux中Kipmi0进程对CPU使用率很高问题

突然top发现Kipmi0进程一直占用近乎100%的一个核的资源,并且已经持续了很长一段时间。

google查不到多少资料,看到一篇说法:是一些平台接口的管理器。不敢贸然杀死,再查查资料。

看看专业的说法:
kipmi is supposed to run with low priority. When you say it consumes 70-90% of the CPUs, is that constant (does it still consume the processor when they are other tasks in the process queue that should have a larger slice of the CPU time) or the 70%/90% comes when the machine is idle?
A second issue to investigate is whether you have pending controller issues (alarms of varying nature that are not resolved) and/or older versions of controller firmware.
这是一个利用空余的CPU资源进行一些接口自动调节的任务.
临时解决方案
echo 100 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us
执行完之后

执行上面命令后,所占CPU单核资源从100%降低到10%
