I use Minstall to do setup a basic webserver to run three very basic Wordpress sites. The VPS ia a 1gb server, so should be more than enough for the job.
The issue I am finding is that, according to the monitors I have set up with uptimerobot, the websites suffer from downtime once or twice a day, reporting a Bad Gateway error. The downtime seems to last a few minutes then recovers.
In addition to this, I have found that the server itself is restarting once or twice a day (I have a monitor for each website, and a ping monitor for the server IP). I can only assume that my nginx / php-fpm configuration is causing the restarts. Can anyone help me pin point the issue and fix it?
