Hi,

I am getting below issue on starting kibana 7.9.1 on ubuntu(8GB RAM) machine and its stuck at this point.

[BABEL] Note: The code generator has deoptimised the styling of /export/home1/Elk\_Setup/kibana-7.9.1-linux-x86\_64/x-pack/plugins/canvas/server/templates/pitch\_presentation.js as it exceeds the max of 500KB.

If I kill the process then getting below.

Hey,

Node has a default max memory usage of less than 2GB on most machines. Can you try to increase Node's heap size when running kibana?
