[gpBlockchain]

1. call receive_btc 10times will cause Too many open files (os error 24)

        for i in range(10):
            fiber2_invoice = self.fiber2.get_client().new_invoice({
                "amount": hex(100),

                "payment_preimage": self.generate_random_preimage()
            })
            fiber2_invoices.append(fiber2_invoice)
