Is there a way, to make the clients rebalance on Artemis Cluster?

[He...@systema.com]

Hello team,

we are running three artemis brokers A,B,C in an "all active" 
configuration.
The clients use failover transport (A,B,C)?failoverAttempts=-1 and when 
the clients startup they distribute on the brokers just fine.
When broker A is restarted, clients fall to the other brokers. Still looks 
good so far. 
If broker B is restarted, the clients do not go back to A they all end up 
on C.
Having all clients on one broker is not loadbalanced and restarting the 
clents is not an option.
Did we configure something wrong? would it help to start with different 
sequences in the url (A,B,C), (B,A,C) etc. ?

Regards

Herbert

It doesn't sound like you're doing anything wrong. However, it does sound
like you might want a connection router [1] configured on each broker in
the cluster to help keep things balanced.

Other things to keep in mind:
 - The management API provides the ability to close client connections,
forcing them to reconnect.
 - Your cluster might be too large [2].
