Increase swap partation size

first check whether you have already swap partation and its size

grep Swap /proc/meminfo

check ram size

if your swap+ram size is less then 48 GB then create a swap partation of size = (48 - ramsize)

to create swap partation

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1M
sudo chmod 0600 /swapfile
sudo mkswap /swapfile 

sudo swapon /swapfile  # Turn the swap on

If you want to make a 4 GiB file, then change count value to count=4M

make it parmenent

vim /etc/fstab

# Add this line to the end
/swapfile swap swap sw 0 0
