Issue

• How to keep socket open ?
• I am using netty component by customizing a netty endpoint. I would like to send to a tcp server without closing the tcp channel after message dispatching.I configure Netty endpoint like below

        nettyConfiguration.setKeepAlive(                    true );
        nettyConfiguration.setConnectTimeout(               CONNECTIONTIMEOUT );
        nettyConfiguration.setMaximumPoolSize(              MAXPOOLSIZE) ;
        nettyConfiguration.setOrderedThreadPoolExecutor(    true );
        nettyConfiguration.setDisconnect(                   false );
        nettyConfiguration.setLazyChannelCreation(          true );
        nettyConfiguration.setRequestTimeout(               REQUESTTIMEOUT );
        nettyConfiguration.setTcpNoDelay(                   true );
        nettyConfiguration.setDecoders(                     decoders );               
        nettyConfiguration.setProtocol(                     "tcp" );
        nettyConfiguration.setHost(                         HOST );
        nettyConfiguration.setPort(                         PORT );
        nettyConfiguration.setSync(                         false ); 
        nettyConfiguration.setNoReplyLogLevel(              LoggingLevel.ERROR );
        nettyConfiguration.setEncoders(                     encoders );
        nettyConfiguration.setBroadcast(                    false );
        nettyConfiguration.setSendBufferSize(               65536 );
        nettyConfiguration.setReceiveBufferSize(            65536 );
        nettyConfiguration.setReceiveBufferSizePredictor(   0 );

        nettyConfiguration.setNeedClientAuth(               false );
        nettyConfiguration.setSsl(                          false );
        nettyConfiguration.setSslClientCertHeaders(         false );
        nettyConfiguration.setDisconnectOnNoReply(          false );
        nettyConfiguration.setProducerPoolEnabled(          true );
        nettyConfiguration.setServerExceptionCaughtLogLevel( LoggingLevel.ERROR ); 
        nettyConfiguration.setServerClosedChannelExceptionCaughtLogLevel( LoggingLevel.ERROR );

//        nettyConfiguration.setDecoderMaxLineLength(         1024 );
        nettyConfiguration.setAutoAppendDelimiter(          true );
        nettyConfiguration.setProducerPoolMaxActive(        -1 );
        nettyConfiguration.setProducerPoolMinIdle(          0 );
        nettyConfiguration.setProducerPoolMaxIdle(          1000 );
