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).

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