Hi,
With limit 6Gi in 256Gi host, no warning or error in spal_meminfo_get.

Private memory from process ns-slapd get increased
should we try to set DS_MEMORY_PERCENTAGE parameter?

Hello,
389ds docker image acts different in hosts with different amount
of memory.
For example in minikube with 8Gi nodes and limit 6Gi work wells.
But in
a kubernetes cluster with 256Gi nodes and limit 6Gi Pod is
contantly killed.
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

We might have a bug in the autosizing code.
Thanks.
