有很多与内核相关的内容。有人能告诉我是什么原因导致了这个问题吗？

谢谢。
答案1
尝试运行lveinfo --period=1d --by-fault=mem --display-username
找出privvmpages当前设置的内容：
#cat /proc/user_beancounters
在 VEID 下，你会看到如下行：
889489: kmemsize 1420887 2768219 60252800 121278080 0
lockedpages 0 0 550 550 0
privvmpages 8622 18280 500000 750000 0
在这种情况下，privvmpages设置为500000:750000并且没有失败计数。您的失败计数可能会大于 0。要提高 privvmpages，请使用以下命令：
vzctl set VEID --privvmpages XXXXX:YYYYY --save
这会将 VEID privvmpages 设置为XXXXX:YYYYY。
如果这没有帮助，请使用以下步骤并编辑您的帖子：
- 如果可以，请重新启动物理服务器，以清除计数器
- 运行
cat /proc/user_beancounters并保存 - 模拟问题
- 重复步骤 2

我认为值得注意的是这可能是硬件或软件问题，所以我会先尝试解决这个问题。
您能否将其打开但禁用标准处理并查看是否有任何变化，例如关闭所有或大多数进程，这样只有电源和芯片组在运行，但很少进行处理。请注意，这不会使组件过热。因此，您可能还需要尝试运行诸如内存测试或循环压缩算法之类的操作，这将加载 CPU 和总线逻辑，从而导致其电路升温。
如果 20 分钟后它仍然关闭，这听起来像是与热相关的硬件问题。如果你可以把它放进冰箱（认真的）并尝试从那里运行它。如果它继续打开，那么你的某个晶体管坏了。
基本原理：坏的晶体管通常在变热时开始出现故障。有时，您可以冷却坏的（间歇性）晶体管，使其工作。您也可以加热坏的间歇性晶体管，使其出现故障。.. 是的，您的服务器只有十亿个晶体管左右（包括电源中最重要的高功率晶体管，它们最容易出现故障）。您还可以用热风枪小心地加热主板，有时会导致主板出现故障。好的主板在相当热的温度下运行不会出现故障，但长时间处于高温状态会缩短其寿命（请参阅有关“浴缸曲线”的信息）。
如果它没有关闭，请通过二分法找出哪个进程可能导致问题，这是我所知道的解决问题的最快方法。例如，尝试启动大约 1/2 的进程（不太依赖于其他事物的进程）。
您还可以将一些硬件与另一个系统进行交换，例如电源，以帮助理清各个硬件的区别。
