Node.js сбой во время сборки углового 6 с --watch

Я использую Node v8.12.0 на Mac (хотя я видел эту проблему с версиями Node 9.x, а также в Linux).

Я разрабатываю приложение Angular 6 и запускаю dev с --watch флага --watch. Часы будут работать и могут перестроить приложение, возможно, 4 или 5 раз, затем Node выйдет со следующим выходом:

Я также попытался добавить --max_old_space_size=12000, но это, похоже, не имеет никакого значения. Я не уверен, где искать причину проблемы или как начать отладку в узле. Любая помощь была бы чрезвычайно оценена!

Некоторые предпосылки: это приложение Angular 5 с выталкиваемой конфигурацией, и я обновил его до Angular 6 с той же конфигурацией, и само приложение работает должным образом. Только с момента обновления к Angular 6 этот вопрос начал возникать.
