Hi, This morning, while checking for a correct deployment, we found out that the Unicorns we are using were sending 500 Internal errors very frequently to the HAProxy that sits in front of them. After some investigation, It turned out that HAProxy checks the backend by opening and closing a connection to the unicorn.
