boost::asio::acceptor hangs up on win7 - c++

Question

I've implemented simple boost::asio program that starts tcp connection.
It works perfect on linux (ubuntu 12.04, boost 1_48, gcc 4.6.4),
but not on Win7 (boost 1_55, vs2008express).
After accepting few (from 3 to 20) connections it hangs up, and doesn't accept connections anymore.
Is it some windows protection problem? I turn off firewall and antivirus.
Here is the code for reference:
#include <iostream>
#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/enable_shared_from_this.hpp>
class Session : public boost::enable_shared_from_this<Session>
{
public:
Session(boost::asio::io_service &io_) : tcpSocket(io_)
{
std::cerr << "session ctor" << std::endl;
}
~Session()
{
std::cerr << "session Dtor" << std::endl;
}
boost::asio::ip::tcp::socket& getTcpSocket() { return this->tcpSocket; }
private:
boost::asio::ip::tcp::socket tcpSocket;
};
class Server
{
public:
static const unsigned int defaultPort = 55550;
Server();
void start();
private:
boost::asio::io_service io;
boost::asio::ip::tcp::acceptor acceptor;
void startAccept();
void handleAccept(boost::shared_ptr<Session> s_,
const boost::system::error_code& e_);
};
Server::Server()
: acceptor(io, boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), defaultPort))
{
}
void Server::start()
{
this->startAccept();
this->io.run();
}
void Server::startAccept()
{
boost::shared_ptr<Session> s(new Session(io));
acceptor.async_accept(s->getTcpSocket(), boost::bind(&Server::handleAccept,
this, s, boost::asio::placeholders::error));
}
void Server::handleAccept(boost::shared_ptr<Session> s_,
const boost::system::error_code& e_)
{
std::cerr << "handleAccept" << std::endl;
if(e_)
std::cerr << e_ << std::endl;
this->startAccept();
}
int main(int, char**)
{
Server server;
server.start();
}
EDIT:
Problem solved. It was Cygwin problem.

It could be that the Win7 acceptor requires the option to reuse the address: i.e. SO_REUSEADDR.
Try changing your server constructor to:
Server::Server()
: acceptor(io)
{
boost::asio::ip::tcp::endpoint endpoint(boost::asio::ip::tcp::v4(), defaultPort);
acceptor.open(endpoint.protocol());
acceptor.set_option(boost::asio::ip::tcp::acceptor::reuse_address(true));
boost::system::error_code ec;
acceptor.bind(endpoint, ec);
if(ec)
// raise an exception or log this error, etc.
}
