Question
Running out of Memory. Driving me nuts
Hi, I have an Ubuntu server with 512 MB Memory and 20 GB Disk.
It is currently running Ngninx and one Wordpress site, and constantly running out of memory.
I have also created a swap file, but it doesn’t help. It stills runs out of memory.
I am out of ideas and articles to read. Please help!

Is mysqld running out of memory?
You might be getting hit with XML-RPC attacks (seems to be a popular thing these days), which cause the out-of-memory condition.
See these two links:

Yes I am having many of these XML-RPC attacks and decided to implement the changes to the vi /etc/nginx/sites-available/wordpress conf.
How can I verify that it works?
Can my server still be underdimensioned because of these attacks?
check for the return code in your access log file. it should change to 500 instead of 200
