+`RestartSec` defaults to: 100ms. Has to be configured with: `Restart`

 I have no idea on how to test this at this time and I am still researching the root cause of the incident, but this was ready a nice extension to my configuration, which is just the default, since everything else is done it the site configuration for NginX.

+Options for restart are:
+
+- `no`
+- `always`
+- `on-success`
+- `on-failure`
+- `on-abnormal`
+- `on-abort`
+- `on-watchdog`
