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.
Path Tasks %CPU Memory Input/s Output/s <PATH> - - 380.6M - -
It is like that all the time. Any ideas?
