Re: Address already in use?

[Maarten Bosteels]

Hi Aneel,

try adding these two lines:

SocketSessionConfig config = (SocketSessionConfig) acceptor.getSessionConfig
();
config.setReuseAddress(true);

This will set reuseAddress true for all accepted sockets.

I've been having a problem that I thought I knew how to resolve: If I
stop my Mina (1.1.0) server when it has clients connected, and then try
to immediately restart it, I get a BindException complaining that the
address is already in use. When this happens, netstat shows some
connections in TIME_WAIT, but nothing listening on the port.

I thought that setReuseAddress would fix this problem, but it doesn't
seem to. Am I missing something?

Here's the piece of my code with the bind in question:

         // Prepare the configuration
         SocketAcceptorConfig config = new SocketAcceptorConfig();
         config.setReuseAddress( true );

         // Bind the the User Handler to its address
         userAcceptor = new SocketAcceptor();
         System.out.println( "Running " + userHandler + " on " +
this.userAddress );
         System.out.println("Reuse? " + config.isReuseAddress());
         userAcceptor.bind( this.userAddress.getSocketAddress(),
userHandler, config );


On stdout I see:

Reuse? true


But I get:
