Issue¶

Memory consumption issues in Composer builds.

Resolution¶

Consider adding the composer optimizations project, to remove legacy Symfony builds with: 

composer require zaporylie/composer-drupal-optimizations

See more information about the project: https://github.com/zaporylie/composer-drupal-optimizations
