cgroup memory way below the total and the system is idle besides running vms (loads of memory left for other tasks out of the cgroup). For the record, my system has 32GB and I was using 20GB for the guests cgroups. Here is part of the the crash log (it is veeery long but I ...
看网上的解释:The “OOM Killer” or “Out of Memory Killer” is a process that the Linux kernel employs when the system is critically low on memory. 看网上有人说建立swap分区会好一些,那我只好建了一个400M的swap分区文件。 === 已上并没有什么卵用,下面分析一下oom kill的log Aug 23 22:26:...
实质为进程数据结构中的一个变量,用来表示发生 Out of Memory 时杀死进程的优先级顺序。lowmemorykiller 利用这个变量对进程的重要程度进行判断,并在内存不足时释放部分空间,其实现在文件 /kernel/drivers/staging/android/lowmemorykiller.c 中。lowmemorykiller 定义了两个数组:lowmem_adj 和 lowmem_minfree。其中 l...

memory -- 这个子系统设定 cgroup 中任务使用的内存限制,并自动生成由那些任务使用的内存资源报告。 net_cls -- 这个子系统使用等级识别符(classid)标记网络数据包,可允许 Linux 流量控制程序(tc)识别从具体 cgroup 中生成的数据包。 ns -- 名称空间子系统。

ALLOC_CPUSET 表示内存只能在当前进程所允许运行的 CPU 所关联的 NUMA 节点中进行分配。比如使用 cgroup 限制进程只能在某些特定的 CPU 上运行,那么进程所发起的内存分配请求,只能在这些特定 CPU 所在的 NUMA 节点中进行。 ALLOC_KSWAPD 表示允许唤醒 NUMA 节点中的 KSWAPD 进程,异步进行内存回收。
