Hello there, I have tried to implement a simple echo server using the network-conduit library version 0.2.1. This is the code: module Main where import Data.Conduit import Data.Conduit.Network main :: IO () main = runTCPServer (ServerSettings 4000 Nothing) ($$) It works, but at some point it dies with too many open files, even though I never open two connections simultaneously: % ./echo-server echo-server: accept: resource exhausted (Too many open files) Apparently it fails to close the sockets properly. This is the client side code I have used for testing in GHCi: > :m Network Control.Monad System.IO > replicateM_ 512 (connectTo "127.0.0.1" (PortNumber 4000) >>= hClose) I'm running the action once, then wait a few seconds to give the server a chance to close the handles. Then I run it again, causing the server program to die with the above mentioned error message. Am I doing something wrong or is this a bug in network-conduit?
