ssh2_scp_send第一次没问题，但第二次失败了

Question

I am making use of php ssh2_scp_send to transfer files to the remote machine, but it is a bit weird, it works for the first time but fails my second call with the following error

//success for file transfer
if (!(ssh2_scp_send($this->conn, $lpath, $rpath, 0777))){
            throw new Exception("File transfer failed!");
        }
        ssh2_exec($this->conn, 'exit'); 

//fail this time
if (!(ssh2_scp_send($this->conn, $lpath, $rpath, 0777))){
            throw new Exception("File transfer failed!");
        }
        ssh2_exec($this->conn, 'exit')

"Warning: ssh2_scp_send(): Failed copying file in /var/www/trunk/rsetting/class/ssh.class.php on line 57"

Any help will be appreciated~Thanks

update php-ssh2 extension to 0.13 will be fine.
