Hi Peter,
Thanks for your response.
Usually, when my load balancer stop balancing, it stops to work only on one
virtual server (and most of the time, it stops on the same VIP) and then,
all the http requests are directed to one real server (always the same too).
So it's look like to the arp problem ?
Cyrille.
