I'm using MINA 1.1.7 on android (2.2 emulator) to connect to my MINA
server implementation.
My client runner looks like this:
public void init() {
connector = new SocketConnector();
connectorConfig = new SocketConnectorConfig();
connectorConfig.setConnectTimeout(SOCKET_CONNECT_TIMEOUT_IN_SECONDS);
connector.setWorkerTimeout(WORKER_THREAD_TIMEOUT_IN_SECONDS);
connectorConfig.getFilterChain().addLast("codec", new
ProtocolCodecFilter(getCodecFactory()));
}
public void run() {
try {
LOG.info("connecting to gateway host={}, port{}", host, port);
ConnectFuture connectFuture = connector.connect(
new InetSocketAddress(host, port),
clientSessionHandler, connectorConfig);
connectFuture.join(CONNECT_JOIN_TIMEOUT_IN_MS);
IoSession session = connectFuture.getSession();
LOG.debug("Connected: {}", session.getLocalAddress());
CloseFuture closeFuture = session.getCloseFuture();
closeFuture.join();
LOG.debug("Session complete: {}", session.getLocalAddress());
} catch (Exception e) {
LOG.error("unable to initiate session", e);
} finally {
}
}
The client is run using a ScheduledExecutorService and runs every
minute to connect to the server and do a message exchange. After
running for some period of time I get this:

As I understand it, I should be able to reuse the socketconnector. Is
there a reason that things aren't being cleaned up after the session?
Is there something else I need to configure? FWIW, I tried upgrading
to 2.0 in the past and ran into problems that noone was able to
resolve so that's really not an option for me unless the previous
issue I encountered has been fixed:
