Cannot allocate memory: fork: Unable to fork new process?

Question

We have our hosting in aws. Recently after moving our blog from wordpress to aws, we are experiencing noticeable delay in server response

Answer 1

I've face that problem either while hosting a java app with jenkins, mysql & tomcat on ubuntu on an vm of AWS.

First steps I used to solve the problem with restarting a vm.

AWS doesn't give swap memory on a harddrive by default, so you'd better to make it with your hands. How to do this you can find here. Need to mention: the solution with swap zone (have no idea why) haven't work for me, I had to create a swap file.

Good luck to you!
