Hello, I have an unexpected behavior on redelivery with artemis.
The documentation states that redelivery is attempted 10 times by default and that -1 means infinite (https://activemq.apache.org/components/artemis/documentation/2.10.1/undelivered-messages.html) (I checked the documentation matching version to be sure, but it seems identical in latest) I have queues with max-delivery-attempts set to -1 (in <address-setting>, per queue). I checked the live queue properties in JMX, it matches the xml configuration with -1 so a configuration loading issue is not supected. Now I have broken connexions on consumers (more on that later) and the message is trashed after six attempts. It produces the following (<redacted>) log statements 2021-01-06 16:56:28,016 WARNÂ {Thread-16 (ActiveMQ-server-org.apache.activemq.artemis.core.server.impl.ActiveMQServerImpl$6@f493a59)} [org.apache.activemq.artemis.core.client] : AMQ212037: Connection failure to /xxx.xxx.xxx.xxx:49918 has been detected: AMQ229014: Did not receive data from /xxx.xxx.xxx.xxx:49918 within the 30,000ms connection TTL.

No Dead Letter Address configured for queue <address> so dropping it the 6 redelivery attempts seems consistent with this other documentation : https://access.redhat.com/documentation/en-us/red_hat_amq/6.3/html/client_connectivity_guide/amq-redelivery So, any clue why we get this behavior ? Did I get the meaning of the configuration directives wrong ? Is there a bug in the documentation and/or artemis ? Regards, SL
