Thanks for testing. I've looked at your trace. I'm not seeing any abnormal behaviour there. However I'm seeing lots of 503 responses returned by the server. Could it be that your client retries on 503, leading to an increase of the load ? It could also possibly explain why this happens after some time (i.e. if the servers start to fall after some time). Also I'm seeing that you're having a lot of short connections. Maybe you're accumulating a large number of idle connections to the backend servers. Could you please try to add "http-reuse always" to your backend(s) to see if that improves the situation ? Thanks, Willy
