After I saw the log, it complain virtual memory exhausted: Cannot allocate memory

Exactly the same like this issue. Instead of using $5/mo droplets, it needs 4 GB for swap space($20/mo) when it has memory leaking problems.

After I resize my droplets to $20/mo, everything is fine now.
And.... Yes, I resize it back to $5/mo, after I've done with installing.

Just let you know that, maybe you want to update your blog?
