This is excerpt from one of my projects.

Initialisation:

#if defined(WIN32)
WSADATA wsaData;
WORD wVersionRequested = MAKEWORD(2, 0);
if (WSAStartup(wVersionRequested, &wsaData) != 0) {
  LOG("WSAStartup() error");
  return false;
}
#endif

serv_socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);

...

Cleanup:

#if defined(WIN32)
  /* winsock requires a special function for sockets */
  shutdown(serv_socket, SD_BOTH);
  closesocket(serv_socket);
  /* clean up winsock */
  WSACleanup();  
#else
  close(serv_socket);
#endif

Hope this helps.

Couldn't resovle and find the problem.The application is using more than just sockets. Although Microsoft reference sais that onevery WSAStartup you must use WSACleanup, well this is not true and the system is releasing things regards that.
