Si tratamos por ejemplo de realizar un composer update en una instancia EC2 y nos devuelve el error Cannot allocate memory PHP Fatal error: Out of memory (allocated 745545728) (tried to allocate…)
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 PHP Warning: proc_open(): fork failed - Cannot allocate memory in phar:///usr/local/bin/composer/vendor/symfony/console/Application.php on line 967 Warning: proc_open(): fork failed - Cannot allocate memory in phar:///usr/local/bin/composer/vendor/symfony/console/Application.php on line 967
Haremos lo siguiente:
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024 sudo /sbin/mkswap /var/swap.1 sudo chmod 600 /var/swap.1 sudo /sbin/swapon /var/swap.1
