> Reason: The ChangeEventQueue may get too many events because of little delay of network.
> The ChangeEventQueue is writen data to be full before it is called to disconnect the binarylog client connection.
> Solve: The data  is not necessary when the the task is not running. I think we can avoid the ChangeEventQueue to be full by adding these code lines.

> Is it right to work in this way? Can anyone check this?
