Automatically restart HHVM if a url is returning a 502. I'm using the HHVM nightlies to take advantage of some new features, but it will occasionally stop responding to requests. Add this to your crontab to run every minute.

autorestart.sh

#!/bin/bash

response=$(curl -L --write-out %{http_code} --silent --output /dev/null jason.stallin.gs);
echo $response
if [ "$response" = "502" ]
then
service hhvm restart
fi

Looks promising. Because I still get 502 sometimes. How to use this? I'm not sure if * * * * * /root/autorestart.sh wil work as a cronjob

That worked for me! Sorry just saw this.
