boost thread and socket

I have a very weird problem. In server class, if I comment t1.join() I can not read anything from the socket in the HandleFunction. But if I uncomment t1.join(), that works just fine. But I need this listen function run forever and create a thread to handle the socket whenever it accept one. If i add join there will definately create some problem. How can i fix it? thanks in advance

class server
{
  io_service;
  acceptor;
  void listen()
  {
  for(;;)
  {
    boost::asio::ip::tcp::socket socket(io_service);
    socketPtr = &socket;
    acceptor.accept(socket);
    HandleClass objHandleClass;
    boost::thread t1(boost::bind(&HandleClass::HandleFunction, &objHandleClass, boost::ref(socketptr)));
    //t1.join();
  }
  }
}

int main()
{
  server objServer;
  objServer.listen();
}

class HandleClass
{
  HandleFunction(socket* socketPtr)
  {
    //read from this socket;
  }
}

In your loop inside void listen()

for(;;)
  {
    boost::asio::ip::tcp::socket socket(io_service);
    socketPtr = &socket;
    acceptor.accept(socket);
    HandleClass objHandleClass;
    boost::thread t1(boost::bind(&HandleClass::HandleFunction, &objHandleClass, boost::ref(socketptr)));
    //t1.join();
  }

Your socket object will go out of scope and be destroyed every iteration of this loop, this is why you cannot read from the socket when t1.join() is commented out.
