Keepalive: "single" parameter deprecated. The original idea was to optimize edge cases in case of interchangeable backends, i.e. don't establish a new connection if we have any one cached. This causes more harm than good though, as it screws up underlying balancer's idea about backends used and may result in various unexpected problems.
