The code is below. [code omitted] Hmm... Do you see the same issue if you use a Racket custodian to clean up the resources? The Systems tutorial talks about custodians a bit: http://docs.racket-lang.org/more/index.html#(part._.Terminating_.Connections) Your code would't have to change too much: it'd look something like: (define cust (make-custodian)) (parameterize ([current-custodian cust]) ;; .. your code, which opens ports and does other stuff (custodian-shutdown-all cust)) If you open ports in the context of a custodian, that custodian takes responsibility for cleaning up resources when custodian-shutdown-all gets called. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
