We experienced the issue on both 2.24 and 2.25. When we downgraded to 2.20 we 
haven't experienced the problem anymore.

When we were producing to the address on the nodes there were no consumers on 
the underlaying anycast queue. There where other producers/consumers present in 
the cluster but they were on different addresses/queues. Our addresses all have 
a one-to-one relationship with a any cast JMS queue.

what version are you using:   beware of ARTEMIS-3862 Short lived
subscription makes address size inconsistent


Are you sure 2.20 would fix it? I am not aware of any difference that
would make it so.


do you have the replica taking over on your tests?
