Summary0014172: oom crashes the machine
DescriptionI am running a Kubernetes cluster composed of CentOS-7 machines. I detected that whenever the cgroup where the kubernetes pods & kubelet cannot allocate more memory. The machine crashes. It seems to be related to an oom error that crashes the Kernel.

I tried to set `vm.overcommit_memory=1` or to `2` but I get the same result. I followed what suggested in this page https://docs.openshift.org/latest/admin_guide/overcommit.html. But I believe there should be something else to configure when using CentOS.

Primarily I'd like to avoid my machine to crash due to this oom problem. How can I achieve this contention ?

NAME="CentOS Linux"
VERSION="7 (Core)"
ID_LIKE="rhel fedora"
PRETTY_NAME="CentOS Linux 7 (Core)"


Steps To ReproduceI create process inside one cgroup allocating more memory that the one available for this cgroup.
