java.rmi.ConnectIOException: error during JRMP connection establishment;

Question

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！

估计是内存没有释放的原因，因为你提供的信息不详细，没法准确给出答案。
你可以在代码中加入输出当前内存清空的代码。
package test;

import java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
public class OSTest {
public static void main(String[] args)
{
OperatingSystemMXBean osmb = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
System.out.println("系统物理内存总计：" + osmb.getTotalPhysicalMemorySize() / 1024/1024 + "MB");
System.out.println("系统物理可用内存总计：" + osmb.getFreePhysicalMemorySize() / 1024/1024 + "MB"); }
}追问

好的 我试试，不行的话 我把详细代码给你 帮我看看 这个都成心病了，跑一天就出错
