We were polling DB based on hostname which could in some occasions resolve to a different container preventing the app from starting. We now poll based on IP.
We also hadn't updated the MySQL configuration file for existing installs. Fresh installs get the latest config file but existing installs were stuck on the previous version.
max_connections
was increased from 20 to 80 and not running the new higher limit causes the Node.js process to get disconnected from the DB.
