Question

My issue seems to be related to:
https://issues.jboss.org/browse/NETTY-433

I’m trying to stop my Netty server but this call never returns:

serverBootstrap.releaseExternalResources();

It’s looping forever in the ExecutorUtil.terminate method when trying to shutdown the worker ThreadPoolExecutor:

org.jboss.netty.util.internal.ExecutorUtil.terminate()
   for (;;) {
       es.shutdownNow(); 
       es.awaitTermination..
   }

The problem is I don’t have any control over the Client connecting to my Server. Is there a way for the server to force the server to stop and simple close the channel and stop worker threads?

Answer 1

What you can do to ensure that your child channels are closed before you do a releaseAllResources is to register all created child channels in a ChannelGroup. When you shutdown, you can call close() on the ChannelGroup and this will close all the channels in it.
