You can throw this into lib/core_ext in your rails app to prevent implicit connections being made with a stack trace to track down the errant code.

	# This is hacked from the original code for Rails 4.1. Owen went in and hacked the ConnectionPool
	# so it's not fool proof but prevents ShopHotelsCommand from grabbing dozens of idle DB connections.
	#
	# If you create a thread yourself, if it uses ActiveRecord objects without
	# explicitly checking out a connection, one will still be checked out implicitly.
	# If it is never checked back in with `ActiveRecord::Base.clear_active_connections!`,
	# then it will be leaked.
