问题: kernel_task进程疯狂写数据到硬盘

MAC OS 10.13.1 (17B1003) 于11月18号从10.9.5升级到10.13.1

kernel_task进程疯狂的往硬盘写数据,写满硬盘后删除,然后继续写。今天早上9点左右出现该问题,重启无数次+TM恢复昨天的备份,问题依然存在。。。。。。

有人碰到同样问题或知道怎么解决吗?求解决方案😟

下图是从早上9点到中午12点的硬盘使用情况,不停的写满删除,写满再删除。。。。。。

回答:

kernal写数据,有可能是比如内存不够,它往硬盘写可以临时从内存卸载的数据到硬盘,或者是某个程序通过kernal在大量写数据处理大数据,比如打开了大量照片或视 频等文件。还有一种可能是某个程序出错了,还有可能是系统服务出问题,比如Spotlight。


看到你是从10.9.x升级过来呢,那么有可能有的程序不兼容。


也可以使用EtreCheck软件,生成更详尽一些的系统状况报告,可以参见我的博客:macOS: 使用EtreCheck搜集系统信息以自检和获得生成报告。当然,这个软件提供的报告虽然详尽些,但是并不能单单依据它看出系统所有的问题。


如果要快捷,就备份数据后,抹盘重装系统。

感谢您的帮助.

这个是内存情况,知道那个用了15G的进程是什么吗?Spotlight已经关闭了,我明天用EtreCheck检查下,再发上来,备份数据抹盘重装和从TM恢复不一样吗?意思是我要手动拷出所有数据,重装一个干净的系统,然后再把数据拷回来?如果是这样,那我的 TM是不是要从重装的那一刻开始?以前的都没有了?

一般来说,使用TM备份和恢复就可以。本人一般建议,重做系统之后,用户数据可以全部恢复,但不立刻恢复所有原来安装的软件,否则和没有重装差别不大,因为各种问题很可能 就是某些软件造成的。


分三步走:

  1. 抹盘重装后,先观察系统运行情况
  2. 没有问题,逐步安装比较靠谱的和必须用的软件,正常使用的同事密切观察系统状况
  3. 没有大问题,再逐步安装其他辅助软件,比如你截图中的那个软件

这样可以逐步缩小范围,看是哪个程序安装后产生问题。另,更新到最新版本或者适配你的操作系统版本的版本。


前面帖子有个人也是报告UserEventAgent占用过大.

嗯...
