PHPStan memory issues

Cause

PHPStan needs to parse all files and because of Spryker’s magic with resolving classes, e.g., $this->getFacade(), PHPStan needs to look up this class on its own when the @method annotation is missing.

Solution

Run PHPStan in debug mode --debug on the module where it needs too much memory. In the debug mode, PHPStan will display the file name currently being analyzed. If PHPStan gets stuck at a specific file, look into this file and check if all @method annotations are present.
