I am using the Auto-Annotated Portfolio template, which has built-in visual editing. The config and deploy preview work, until I try to edit something with the visual editor, at which point the preview server auto-shutdowns.
I have re-created the project from scratch with no changes several times to verify that this is a template problem, and not a result of my changes.
The problem appears to be with an EventEmitter memory leak, potentially in the visual editor or actual template configuration.
It does not appear to be a preview server resources limitation, as the displayed readouts remain low.
The relevant part of the preview server log is:
Feb 12, 02:42:33 AM: (node:5216) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 26 close listeners added to [Server]. MaxListeners is 25. Use emitter.setMaxListeners() to increase limit
