You want scary - I'll give you one. Have you ever thought what do these number in uptime(1) mean? If you thought 'a number of processes that's waiting for CPU' - think again - [1]. And yes, only Linux kernel counts uninterruptible sleep as load average. As for the disappointment - I have it too. Fresh one: Mar 7 09:11:17 xxx kernel: [315045.065234] systemd-udevd invoked oom-killer: ... Mar 7 09:11:18 xxx kernel: [315045.301642] Free swap = 3887244kB Mar 7 09:11:18 xxx kernel: [315045.305155] Total swap = 3903484kB Mar 7 09:11:18 xxx kernel: [315045.308669] 65536 pages RAM Use swap, they said. If you don't configure swap, big scary out-of-memory killer will take your processes, they said. [1] http://www.brendangregg.com/blog/2017-08-08/linux-load-averages.html Reco
