java.rmi.ConnectIOException: error during JRMP connection establishment,该怎么处理

java.rmi.ConnectIOException: error during JRMP connection establishment
描述：我有个类代码如下，在main方法中调用，每10秒钟调用一次，开始运行没问题，运行一天左右就报错
public void excuteAlarm() throws ParserConfigurationException,
SAXException, IOException {
setCtx(new FileSystemXmlApplicationContext("classpath:applicationContext.xml"));
setEntityManagerFactory((EntityManagerFactory) ctx.getBean("entityManagerFactory"));
EntityManager em = entityManagerFactory.createEntityManager();
// 取得监测数据
String COUNT_ALL = "。。。。。。。。。 ";
 
int count = ((Number) em.createNativeQuery(COUNT_ALL).getResultList().get(0)).intValue();
 
if (em.isOpen()) {
em.close();
}
EntityManagerFactoryUtils.closeEntityManager(em);
 
System.out.println("要处理的所有对象总数" + count);
 
List<RmiService> rmiServiceList =getPropertyValue();//取到服务的个数

if(rmiServiceList == null || rmiServiceList.size() == 0){
logger.warn("找不到运行状态的服务器");
}else{
int ServiceCount = rmiServiceList.size();
int eachService = count / ServiceCount;
for (int i = 0; i < ServiceCount; i++) {
int[] wellData = { i*eachService+1, (i+1)*eachService };
if(i == (ServiceCount - 1)){
wellData[0] = i*eachService+1;
wellData[1] = count;
}
String[] ThreadPoolParam = { "1", "4", "4", "1" };

AlarmClientThread  alarmClientThread = new AlarmClientThread(ThreadPoolParam,wellData,rmiServiceList.get(i).getUrl());
Thread thread =new Thread(alarmClientThread);
logger.info("转换从"+wellData[0]+"到"+wellData[1]);
thread.start();
}
 
}
}


报错如下各位大神求解！
