netty issue

[Sadanand Kusma]

I am actually trying out asynchronous messaging with Netty producer. I get 
below exception even though sync =false. Also, Is this  the right way to 
implement asynchronous processing.
Here is my route:
            
from("netty:tcp://localhost:6205?textline=true&sync=true").process(new 
Processor() {
                int i=0;
                  public void process(Exchange exchange) throws Exception {
                    String body = exchange.getIn().getBody(String.class);
                        Thread.sleep(2000);
                    exchange.getOut().setBody("Bye 1" + body);
                }
            });

            from("file:///test/test/response")
            .convertBodyTo(String.class)
            .threads(1)
            .to("netty:tcp://localhost:6205?textline=true&sync=false")
            .to("log:+++ reply++++");


org.apache.camel.ExchangeTimedOutException: The OUT message was not received 
within: 30000 millis. Exchange[GenericFileMessage with body: Bye 1hello2]
