Auto respond emailer stops

Question

Hi
We have developed an email application, to give auto response to the mails based on the body of the text. Sometimes the application stops or terminates. We use the inbox mail properties as
           Properties props = System.getProperties();
            // Setup authentication, get session
            session =  Session.getDefaultInstance(props, null);
            session.setDebug(debug);
            // Get the store
            store = session.getStore("imap");
            store.connect(mailServer,userName, password );
            // Get folder
            folder = store.getFolder("INBOX");
            folder.open(Folder.READ_WRITE);send mail properties as
//Set the host smtp address
            Properties props = new Properties();
            props.put("mail.smtp.host", smtpHost);
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.connectiontimeout", "120000");// 2 minutes
            props.put("mail.smtp.timeout", "120000");// 2 minutes
            props.put("mail.smtp.quitwait", "false");
            Authenticator auth = new SMTPAuthenticator();
            Session session = Session.getInstance(props, auth);Can you please tell me, what might be the problem ?
Thanks

Hi bshannon ,
Emailer application is running.It is not responding to the new emails. I think the mailer server might be down. We used the following code.
int freq = 1000;
                int cnt = 0;
                for (; ;) {
                    try{
                        // sleep for freq milliseconds
                         Thread.sleep(freq);
                         if(!store.isConnected())  
                             System.out.println("session  "+ session);
                             store = session.getStore("imap");
                             store.connect(mailServer,userName, password );
                         if(!folder.isOpen())
                              folder = store.getFolder("INBOX");
                              folder.open(Folder.READ_WRITE);
                               folder.addMessageCountListener(new MessageCountAdapter(){
                                    public void messagesAdded(MessageCountEvent ev) {
                                         doProcess(ev);
                        // This is to force the IMAP server to send us
                        // EXISTS notifications.
                        folder.getMessageCount(); 
                        cnt = 0;
                    catch(Exception ex)
                        int temp =  cnt % (30 * 60 * 1000);
                        if(temp == 0) {
                            ex.printStackTrace();
                            cnt = 0;
                        cnt += freq;
}Do we need to create a new session object ?
Can you please tell me the procedure.
Thanks
