Hmmm I did not have a chance to look thoroughly at the code. However
there is a paramter for MINA that we do use that may help you. Look
here ...
// Disable the disconnection of the clients on unbind
SocketAcceptorConfig acceptorCfg = new SocketAcceptorConfig();
acceptorCfg.setDisconnectOnUnbind( false );
acceptorCfg.setReuseAddress( true );
acceptorCfg.setFilterChainBuilder( chainBuilder );
acceptorCfg.setThreadModel( threadModel );
((SocketSessionConfig)(acceptorCfg.getSessionConfig())).setTcpNoDelay(
true );
tcpAcceptor.bind( new InetSocketAddress( port ),
protocolProvider.getHandler(), acceptorCfg );
Make sure you're using the following parameters to the acceptor config.
Namely the reuse address true parameter.
