Author Topic: CPU使用率很高，但是不知道是什么进程导致的…… (Read 16914 times)

ZhangGeng · « **on:** October 06, 2016, 08:21:44 am »

OPNsense 16.7.5-amd64
Intel(R) Xeon(R) CPU E31275 @ 3.40GHz (8 cores)
32G ECC
64G Cfast
2T SATA

开机正常，运行一段时间（有可能一天，有可能一个星期），就会出现CPU占用率的问题，很稳定。按照百分比计算有时候是占用1核心，有时候占用2核心，甚至4核……，一旦CPU使用率高了之后就无法再下来，重启会解决这个问题…… 但我应该怎么搞清楚是什么问题导致的呢。

具体情况请看截图。

CPU占用406.09，查查看吧

ZhangGeng · « **Reply #4 on:** October 09, 2016, 06:09:57 am »

这个显示的是CPU空闲资源，用top -S 累计模式查看的时候他是现实的，刚启动后系统资源充足的时候这个值应该是在800% （因为是8个逻辑CPU），但是现在是400%了，所以少了一半，去哪儿了？干什么了？不知道啊……

有钱大老板,用OPNSENSE的人不多，都在摸索中。你的问题解决了吗？
