针对错误信息 "failed to find memory cgroup, you may need to add 'cgroup_memory=1 cgroup_enable=memory'",这个问题通常出现在系统未正确配置cgroup内存子系统时。以下是详细的解决步骤: 1. 确认错误信息 错误信息表明系统无法找到内存cgroup,这通常意味着cgroup内存子系统没有被正确启用或配置。 2. 研究如何启...

针对超大规格的残留 memory cgroup 进行测试,回收 1 个持有 20G 内存的 memory cgroup,核心回收函数的执行时间分布,基本不超过 64us;不会对其他服务造成影响; 开启内核回收线程后,正常通过内核 LTP 稳定性测试,不会增加内核稳定性风险。 可以看到通过新增一个内核线程对残留的 memory cgroup 进行回收,以较小的资源...
