}

 

void Session::open(bool enableRPCCompression, int connectionTimeoutInMs) {
   ...
   shared_ptr <TTransport> transport(new TFramedTransport(socket));  //here, wrongly create 1 new variable transport, and no code will call this local variable transport->close() to release connection

}

      transport->close();
   }
}
