早上9点左右测试服务器GPS接收服务，发现早上6点作用就已经停止接收数据，说明TCP连接出现异常。打开tomcat的运行日志，不停的出现：
通信错误
Exception in thread "Thread-203" java.lang.NullPointerException
下面是处理TCP长连接的代码（这个代码是不正确的） 附为最近改进的长连接代码：
public void run() {
try {
while(true) {
if(null==socket||null==bis||null==bos)
break;
if(socket.isClosed())
break;
if(!socket.isConnected())
break;
byte [] data = getMessageFromClient();
if(data!=null) {
//转义还原
byte[] receive = util.resEscapeCode(data);
// System.out.println("转移还原后的数据：");
//util.printByteData(receive);
// System.out.println("当前消息ID：");
// util.printByteData(new byte[] {receive[1],receive[2]});
byte[] resp = mts.analyzeData(receive);
sendMessageToClient(resp);
}
}
}finally {
try {
System.out.println("通信错误");
if(bos!=null)
bos.close();
if(bis!=null)
bis.close();
if(socket!=null)
socket.close();
}catch (Exception e1) {
e1.printStackTrace();
}
}
}未发现代码异常出现的位置.
第一次重启tomcat web服务：
中间有错误控制台未看到，启动后不能访问web

中间出现：Caused by: java.net.BindException: Address already in use
再次重启tomcat,服务正常。
不过控制台出现设备不停的重连服务器
连了五次，连接时数据上传正常，9点50左右，出现：

设备已经欠费停机。
现在不是很明白6点停止服务之前发生了什么？如果是停机欠费，后面大概运行了20来分钟是怎么回事？为什么TCP会被断开，设备会一直重连？
附： 长连接代码
public void run() {
try {
while(isRunning) {
if(null==socket||null==bis||null==bos)
break;
if(socket.isClosed())
break;
if(!socket.isConnected())
break;
//现在时间
long startTime = System.currentTimeMillis();
if (startTime - lastHeartbeat > heartBeatInterval) {
System.out.println("心跳失联，断开连接");
isRunning = false;
}
byte [] data = getMessageFromClient();
if(data!=null) {
//转义还原
byte[] receive = util.resEscapeCode(data);
// System.out.println("收到数据：");//默认为心跳
// util.printByteData(data);
//处理心跳
char msgID = util.byteToChar(new byte[] {receive[1],receive[2]});
if(msgID==msgConstant.devHeartBeatID)
lastHeartbeat = System.currentTimeMillis();
byte[] resp = mts.analyzeData(receive);
sendMessageToClient(resp);
}
}
}catch (Exception e) {
e.printStackTrace();
try {
System.out.println("通信错误");
if(bos!=null)
bos.close();
if(bis!=null)
bis.close();
if(socket!=null)
socket.close();
}catch (Exception e1) {
e1.printStackTrace();
}
}
finally {
try {
System.out.println("线程结束");
if(bos!=null)
bos.close();
if(bis!=null)
bis.close();
if(socket!=null)
socket.close();
}catch (Exception e1) {
