Please provide a working test application, instead of partial code.

Hi,
I am using mina 1.1.7 and try to simulate many client to a server
for stress test.
and I make 50 clientSessoins, each has a SocketConnector, and the
ClientSession.start() is :
private static ThreadPoolExecutor exService = new ThreadPoolExecutor(20,
40, 60L, TimeUnit.SECONDS, new
ArrayBlockingQueue<Runnable>(30),
new ThreadPoolExecutor.DiscardPolicy());
public void start() {
connector = new SocketConnector(4, exService);
SocketConnectorConfig scfg = connector.getDefaultConfig();
scfg.setThreadModel(ThreadModel.MANUAL);
scfg.setConnectTimeout(15);
scfg.getFilterChain().addFirst("mmog_protocol_filter",
new ProtocolCodecFilter(new
MMOGCodecFactory()));
ConnectFuture cf = connector.connect(address, new
ClientHandler());
cf.join();
if (cf.isConnected()) {
session = cf.getSession();
} else {
log.error("could not connect cm");
return;
}
Message m = null;
m = new Message();
m.setCommand(Message.LOGIN);
byte[] body = new byte[16];
byte[] tmp = Util.intToByteArray(streamId);
int p = 0, q = 0;
for (q = 0; q < 4; p++, q++) {
body[p] = tmp[q];
}
tmp = Util.floatToByteArray(x);
for (q = 0; q < 4; p++, q++) {
body[p] = tmp[q];
}
tmp = Util.floatToByteArray(y);
for (q = 0; q < 4; p++, q++) {
body[p] = tmp[q];
}
tmp = Util.floatToByteArray(0);
for (q = 0; q < 4; p++, q++) {
body[p] = tmp[q];
}
m.setBody(body);
WriteFuture wf = session.write(m);
wf.join();
}
The problem is: I new 50 ClientSession and call start one by one :
for (ClientSession cs : sessions) {
cs.start();
log.debug("start id = " + s);
s++;
}
and the log said :

and then it hang!
after "start id = 9" it hanged too! After a while it said could not
connect to server
Why this? Could you please tell me?
Thank you.
