Modx migx fatal error: allowed memory size?

Question

MODX

I display the layout in the resource through the migx plugin, two fields,
title, layout (text field with layout), after some time the error
FATAL ERROR: ALLOWED MEMORY SIZE appears and the editing page of this resource falls, there are not so many migx blocks in the resource - 6 pieces, approximately 500-400 characters of the layout code, what is the reason Mlyn, maybe because of the textarea, which is better than richtext replacements
here is the configuration:
