I suspect its because of Source IP based stickiness. Are you hitting the VIP using the same source ip (e.g users are using a proxy servers using proxy's IP as source).

I don't think it is the problem, even I suspend the server Server13, or shutdown server with 10.122.70.13, it still points to it.


after i remove the sticky srcip configure, not changed

what ever you do won't affect active connections.

You may have to kill all connections.
