"memory cgroup out of memory: killed process" 是一个在 Linux 系统中常见的错误消息,它通常出现在使用 cgroup(控制组)来限制进程资源使用(如内存)的场景中。下面是对该错误的详细解释、可能的原因、解决方法及预防措施。 1. 解释什么是 "memory cgroup out of memory: killed process" 错误 当Linux 系统使用...
3. 在物理机上面查看pod 的cgroup中设置的内存限制,因为,我们没有进行限制,所以默认为pod 的内存大小,其中128974848=123Mi (123*1024*1024). 注意:一旦pod中使用的内存大小超过123Mi,那么cgroup就会kill 里面的进程 cd /sys/fs/cgroup/memory/kubepods/burstable/podbc001ffa-68fc-11e9-92d7-5ef9efd9374c ...
当Java应用程序使用的内存超过系统可用内存时,操作系统会强制终止该应用程序。这种情况通常会在系统日志中出现以下错误信息:Memory cgroup out of memory: Killed process 634542 (java) total-vm:68527080k。本文将介绍优化Java应用程序内存使用的一些技巧和方法,帮助您解决这个问题。 1. 使用合理的数据结构和算法 选择...

这通常是因为某时刻应用程序大量请求内存导致系统内存不足造成的,这通常会触发 Linux 内核里的 Out of Memory (OOM) killer,OOM killer 会杀掉某个进程以腾出内存留给系统用,不致于让系统立刻崩溃。如果检查相关的日志文件(/var/log/messages)就会看到下面类似的 Out of memory: Kill process 信息: 1 2 3 4...

I decided to try disabling the oom-killer on the cgroup and exhaust the cgroup memory to see what happens, and I was expecting the guests to hang until I manually killed one of them (as it is described in cgroup documentation). But surprisingly one of the guests(randomly it seems) gets...
