I have an k8s cluster and one of the pods is crashing because of OOM. It has the limit of 400MB but crashing when pod reaches 30MB and I have no idea why. There is no other process in its cgroup but it still shows there is significant memory usage.

systemd-cgtop output:

Path   Tasks   %CPU   Memory  Input/s Output/s
<PATH>     -      -   380.6M        -        -

It is like that all the time. Any ideas?
