Justin Bertram commented on ARTEMIS-1929:
-----------------------------------------
I've identified a race condition due to concurrent durable subscribers
connecting before the durable subscription is created. I should have a PR soon.
In the mean-time you could potentially work-around the issue by staggering the
start times of your concurrent durable subscribers (although that may be
impossible to coordinate) or you could just retry the creation of the durable
subscription.
