Could you please share the startup log from the container from both
minikube and kubernetes cluster? It prints memory autosizing values.
I noticed on my 128Gi node that it fails to fetch cgroups memory
information and defaults to a large db cache value, even though I limited
the amount of memory to 512Mi:

bash-5.2# cat /sys/fs/cgroup/memory.max
536870912

We might have a bug in the autosizing code.

Thanks.
