Justin Bertram commented on ARTEMIS-5350:
-----------------------------------------
bq. Besides the selectors case, misconfigured redelivery options could also
likely cause issues, leading to messages potentially entering endless retry
loops.
You can mitigate this situation by configuring [{{max-delivery-attempts}} along
with
{{dead-letter-address}}|https://activemq.apache.org/components/artemis/documentation/latest/undelivered-messages.html#configuring-dead-letter-addresses]
so that you never get "endless retry loops." Then you can keep an eye on the
{{MessagesKilled}} attribute for the queue and/or {{MessagesAdded}} attribute
for the queue on the dead-letter address.
