LB_Down

Hello ,

i want to run re select mechanism for Action On Service Down in gateway pool.However, i must perform priority group for members in the pool. So obviously, i'm not fully sure for the configuration. if i set re select , when a member is down that has high value and other member takes over. Doesn't an error occur ? Because i'm thinking that since there is priority group , bigip forwards to other member that is new up. but we don't want to loss existing session as well,

please help me about the matter

Thank you in advance,
