ActiveMQ errors

Hi there,

I have a setup of 10 brokers networked together using Network of Brokers. Recently, after upgrading I start getting the following logs repeatedly:

2023-04-06 16:32:00,710 | WARN  | TopicSubscription: consumer=localhost->localhost-52655-1680710609766-1675:1:1:1, destinations=461, dispatched=1000, delivered=2540251, matched=1001, discarded=0, prefetchExtension=0, usePrefetchExtension=true: has twice its prefetch limit pending, without an ack; it appears to be slow: vm://localhost#5204 | org.apache.activemq.broker.region.TopicSubscription | pool-2786-thread-1

and

2023-04-06 16:32:09,351 | WARN  | Failed to register MBean org.apache.activemq:type=Broker,brokerName=localhost,destinationType=TempQueue,destinationName=ID_BRZPPSYNCB1-56694-1680710578770-1_1_15107 | org.apache.activemq.broker.jmx.ManagedRegionBroker | pool-54-thread-1

Can anyone help my understand them so I can identify where the problem is.

Many thanks

Paul
