As composer troubleshooting guide here This could be happening because the VPS runs out of memory and has no Swap space enabled.

free -m

To enable the swap you can use for example:

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1

Or if above not worked then you can try create a swap file

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
