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
