So I have a small droplet that I run a few small WordPress sites on with Nginx, HHVM, MySQL, etc.
Once a week or so, seemingly randomly, I visit sites on the server and am greeted with a “502 Bad Gateway” error from Nginx. When I investigate further in SSH, I discover that HHVM is not running.
I simply run the “sudo service hhvm start” command and everything comes up and running again.
So I have a couple questions:
Is there any reason why HHVM would suddenly stop running like I’ve described? I believe I have it included in my boot sequence and I regularly update all my packages.
Is there a way to run an automated check, maybe once every five minutes or so to check if HHVM is running, and if not, starting it?
