title: Client channel is not in writable state(NIO) Netty
body: <p>client channel is not in writable state in netty . Can any experts guide me to find-out the reason </p>
  
  <p>why the channel is always not in writable state?</p>
  
  <p>since it is not in writable state our threads are in sleep mode. We analyzed the state of threads using Thread dump, added a counter in the following loop and it waits for a minute and then exit from the loop. But i really want to figure-out the reason for not writable state. </p>
  
  <p>Is the channel is remains in ctx after the closing of channel(If the EOF is not send by the client)?</p>
  
  <p>If can this happends (means never in writable state)?</p>
  
  <pre><code>while (!ctx.getChannel().isWritable()) {
      Thread.sleep(100);
      }
  </code></pre>
  
  <p>Please help.</p>
  
  <p>Thank you very much</p>
