when the mq broker is broken, stomp will throw loop exception

[jiansongjay]

As I say, when the mq is stopped, something happened like that it will throw loop exception. I think bug is on that place.

    // force disconnect, if previous established connection exists
    $this->disconnect();

It cannot write to the socket.
