我正在调查为什么我们的两个进程被
Linux OOM杀手杀死 – 尽管似乎已经有足够的RAM和两次可用的SWAP.
当我将其解释为this answer时,第一个内存请求要求2 ^ 2 = 4页(16KB)的内存(订单标志),并希望它来自“正常”区域.
Jan 27 04:26:14 kernel: [639964.652706] java invoked oom-killer: gfp_mask=0x26000c0,order=2,oom_score_adj=0
如果我正确解析输出,则有足够的空间：
Node 0 Normal free:178144kB min:55068kB low:68832kB high:82600kB
几分钟后第二次有相同的请求 – 似乎还有足够的可用空间.
为什么触发OOM杀手呢？
我解析信息错了吗？
>系统是14.04 Ubuntu,内存为4.4.0-59 x64
> vm.overcommit_memory设置设置为“0”(heuristic),这可能不是最佳选择.
