So for example we have a Pool of 3 Member, Loadbalancing via least connection node 2 Member are in Priority Group 10 1 Member is in Priority Group 5 Activation: less than 2 Each of the 3 member has a connection limit of 100

 

so everything starts fine and Member 1 of Group 10 has reached his connection limit and Member 2 of Group 10 has 80 connections.

 

the next connection(181) CAN be loadbalanced to the Member 2 of Group 10 this is clear

 

i never tested this scenario but i thought the priority group 5 would be activated when connection limit is reached on one member of priority group 10.

 

Archived - K7127: New connection is not directed to the next priority group when the connection limit is reached

    I think in the same way but like you I never saw it in real and was to late to replay it in my lab

     

    The Article you found is for versions <10 so I think this should work now but a real reference would be great

     

    anyway I passed the exam today so the rush for the 301b begins :)
