I don't know how it started or how to reproduce but I can say that we switched
to dual mirroring last night per the current documentation at:
[https://activemq.apache.org/components/artemis/documentation/latest/amqp-broker-connections.html]
In the process we renamed our mirrors (before they had the same name on each
side), and deleted the old mirror queues through the management console after
all of the servers were up. We did this on 4 other pairs (all separate
clusters) without running into this issue.
These errors are coming only from the live server on the disaster recovery
site, which has no consumers except the mirror connection.
Prior to these errors we did have:
2022-03-16 23:52:29,482 WARN
[org.apache.activemq.artemis.protocol.amqp.connect.mirror.AMQPMirrorControllerTarget]
Queue $ACTIVEMQ_ARTEMIS_MIRROR_Mirror not found on mirror target, ignoring ack
for queue=$ACTIVEMQ_ARTEMIS_MIRROR_Mirror, messageID=63165878649,
nodeID=dea32b83-efd5-11eb-b5b1-0050568fe3b2
in our logs, where that mirror name is the old shared mirror name (not part of
the current broker.xml).
Error does not appear to have come back on a restart of the server.
