Question
Ubuntu 2gb Swap File
I was getting a Wordpress database connection error every other day. I created a 512 swap file (1GB droplet) and it made it about a week. I'm trying to increase the swap file 2GB. Here are the steps I took.
sudo swapoff /swapfile
sudo dd if=/dev/zero of=swapfile bs=2048 count=1048576
sudo mkswap /swapfile
It reports: Setting up swapspace version 1, size = 1048572 KiB...
sudo swapon /swapfile
It looks like it only created a 1GB swapfile. When I use free-m it says 1023 for the swap. The file size via WinSCP is 2GB.
Is there a limit on the size of a swap file? If so, can I have two swap files? Or should I get a bigger droplet?

On the original article how-to-configure-virtual-memory-swap-file-on-a-vps , it used count=1000 , I looked at the man page but did not make sense to me. I guess it works either way but wondered what the difference was.
