Updating vlucas/phpdotenv (v2.4.0 => v2.5.1): The following exception is caused by a lack of memory or swap, or not having swap configured Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details
Currently the AWS Instance RAM: 2GB
Though we have fixed the issue by upgrading RAM from 2GB => 4GB but I have few doubts as increasing RAM this should not be the solution for a small site.
Could you please check the following points:
1) What is the recommended memory required by Laravel for updating the packages (composar.phar update)?
2) Does laravel use SWAP memory as well while composer update?
