Ubuntu10.4 Nginx + Wordpress is working only short time and found Cannot allocate memory

  • Posted April 19, 2014

Hi

I tried to install Ubuntu10.4 Nginx + Wordpress and I can load my site just only a short time and got message on Firefox browser "The page you are looking for is temporarily unavailable. Please try again later. "

Then I went back to ssh terminal and trying to check if nginx is running, I found “-bash: fork: Cannot allocate memory”

and whenever I use any command, I found the same message -bash: fork: Cannot allocate memory

then shortly after, It will work again, then after loading a few pages then it lost connection again.

Please help I tried so many times , I followed many configurations from digital ocean but not succeed.

What size droplet are you using? Could you describe your Wordpress set up a little? Do you have a large number of plugins installed? <br> <br>You might want to consider moving to a larger droplet.
