The log message ";; Shutting down HTTP-Kit server" doesn't appear anywhere in the output you supplied so I'm not sure the server's stop lifecycle method is being called and in any case it doesn't appear to actually shut down the server - it just calls (server)... whatever that does... I'm not sure. Good luck. Alan -- You received this message because you are subscribed to the Google Groups "Clojure" group.
