＠＠＠＠＠高手帮帮忙好吗？socket 多线程通信，运行几十次就死锁！

Question

我的程序是这样的，实现SOCKET 通信的服务器端：但测试时运行几十次就顿住了，重新开起这个程序也不行，必须重新启动系统，才行。对不起，分不够了！

socket1=s;
start();
}

public void run(){
try{
InputStream in=new BufferedInputStream(socket1.getInputStream());
//OutputStream out=new BufferedOutputStream(socket1.getOutputStream());
PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream())),true);
 String address=socket1.getInetAddress().getHostAddress();
while(true){

byte[]b=new byte[n];
if(n>0){
int result=in.read(b);
if(result==-1)
{
break;
}

    {
     buf[w]=a[m];
    } for(int i=0;i<h+2;i++)
{

System.out.println(buf[i]);
}String s=new String(buf);

in.close();
} catch(IOException e){

Answer 1

我说错了，是ORACLE数据库死掉了，得重新打开

Answer 2

TO troyzhang(troyzhang)：
设置最大连接数，是说连接池最大连接数吗？

Answer 3

谢谢！我修改了后，现在数据库不会死了，public class teshi extends Thread{

Answer 4

我连接池最大连接数设的是200，现在又出现新的问题：
100个客户端连上来是不会出错，可以顺利查数据库，回复正确响应包，
但1000或10000就会出现ORA-00060: deadlock detected while waiting for resource，或者是：SQLException: ORA-00001: unique constraint (HBS.XAK1ACCOUNT) violated
晕倒！帮帮我好吗？先谢谢你们了！
