UDP connection is not closed

[mangeshgurjar]

var logstash = new Logstash({
type: 'udp',
host: "",
port: ""
});
logstash.send(data, callback);

logstash.send open the socket but no method provided to close the connection which leads to lots of open connections.

UDP doesn't have connections, so there's no open and no close. Perhaps what could happen is that it keeps creating sockets?
