Symfony Commands/Tests running out of Memory? Try `--no-debug`
Raw
main.md

I just spent way too much time chasing an out of memory error when running one of my Symfony Commands. Apparently the Doctrine ORM was holding on to too many entities. I tried flushing, clearing, all the usual stuff, but nothing worked.

Turns out, when running Symfony commands via php bin/console <command-name>, Doctrine's BacktraceDebugDataHolder is used, which NEVER DELETES ENTITIES. This was news to me too. Simply appending --no-debug disables this & seems to fix the issue.

I wish this was made more obvious.
