esme doesn't reconnect after reset connection

[aliasnash]

Hi all, I have a problem with reconnect. When I test code on local machine with smppSimulator - all OK (if I stop simulator and then start it, my esme will reconnect without problems)
BUT when esme work with operator and operator reset connection, esme cant reconnect...(( only some records from log and that's all....maybe thread is dying?
How can I reconnect correctly?

logs from connection with operator:

2013-04-19 14:10:25,471 [EnquireLinkSender: 572b4b6b] INFO 221 :client.gw.AutoReconnectGatewayTrx - Session state of 572b4b6b changed from BOUND_TX to CLOSED
2013-04-19 14:10:25,471 [EnquireLinkSender: 572b4b6b] INFO 252 :client.gw.AutoReconnectGatewayTrx - Session CLOSED, by OPERATOR, let's reconnect

2013-04-19 14:10:29,403 [CL AGW-TX] INFO 203 :jsmpp.session.AbstractSession - AbstractSession.close() called

And if I restart esme, connectiong will establish without problems.
Can somebody help me?
Here part of my code:

class AutoReconnectGateway extends Thread implements Gateway

@Override
public void run(){
    logger.info("GW " + connectionType + " started!");
    String ipAddress = ssetting.getIpAddressMain();
    int port = ssetting.getPortMain();
    session = getSession(ipAddress, port);

    while (isRunning()){
        try{
            if (!isConnected()){
                reloadConnection();
                logger.info("#Try to reconnect after to " + ipAddress + ":" + port);
                session = getSession(ipAddress, port);
            }
            else{
                Utilz.sleep(5000);
            }
        }
        catch (Exception e){
            logger.error("main thread", e);
        }
    }
}

public void reloadConnection(){
    try{
        if (session != null){
            logger.info("closing " + connectionType + " session...");
            session.unbindAndClose();
            session = null;
        }
        else{
            logger.info("session " + connectionType + " already closed!");
        }
    }
    catch (Exception e){
        logger.error("reloadConnection", e);
    }
    logger.info("sleep 10 sec...");
    Utilz.sleep(10000);
}   

public synchronized SMPPSession getSession(String ip, int port){
    if (session == null || !session.getSessionState().isBound()){
        try{
            session = new SMPPSession(ip, port, bindParam);
            session.addSessionStateListener(new SessionStateListenerImpl());
            session.setMessageReceiverListener(new SMPPMessageReceiver(clientQueue, ssetting.getBindType()));
        }
        catch (Exception e){
            logger.error("new " + connectionType + " Session: ", e);
            session = null;
        }
    }

    return session;
}

public boolean isConnected(){
    if (session != null && session.getSessionState().isBound())
        return true;
    return false;
}
