Hello @codejamninja,

please check the limits you are setting for PXC containers.

The way it works is the following:

- We have auto-tuning mechanism

- This auto-tuning mechanism takes the memory (RAM) limits set for PXC containers and based on these limits tunes mysql for better performance

- If memory limits are less than 12 MB - you get this error (see code [here](https://github.com/percona/percona-xtradb-cluster-operator/blob/master/pkg/pxc/app/config/autotune.go#L22-L25)).

But point taken - we will tune the error message to make it clear.
