jjmarin commented on ARTEMIS-5164:
----------------------------------
We have tested version 39, we are still having problems with the counters. We
have also noticed that the consumers are not displayed correctly, the website
tells us that there are consumers but if we go to see them we are told that
they do not exist. Attached are some screenshots. The same error messages keep
appearing in the log. How can we help? Do you need more information about how
we have the architecture or anything else?
