Solution :

Généralement, une mémoire insuffisante entraîne la mort du processus.

Si vous ne pouvez pas augmenter la mémoire physique, vous pouvez envisager d'étendre la partition d'échange.

La référence est la suivante :

composer génère une erreur supprimée lors de l'installation ou de la mise à jour car la mémoire est actuellement insuffisante.

free -m
mkdir -p /var/_swap_
cd /var/_swap_
#Here, 1M * 2000 ~= 2GB of swap memory
dd if=/dev/zero of=swapfile bs=1M count=2000
mkswap swapfile
swapon swapfile
echo “/var/_swap_/swapfile none swap sw 0 0” >> /etc/fstab
#cat /proc/meminfo
free -m
