Hi Francesco, It seems (stickysession + loadbalacing)'s problem and it makes sense to me from another angle. At your user-sessions-01.png and user-sessions-03.png, the first user loop with sticky session was already a little unfair for 2 hours. 8 jboss instance's requests/traffic will be very different after 2 hours(maybe logout) if the first user loop's load is not fair. If I've guessed correctly, the balancing will be fairer if users log out in a short period of time or the first user loop's load is fairer among 8 jboss instances. That's just my opinion. Thanks.
