I'm seeing this message in my AMQ log
[pid: ][ActiveMQ Transport: ssl:///127.0.0.1:56866] 21 Apr 2022 12:36:27 WARN Queue - Usage(default:store:queue://com.queue.error:store) percentUsage=99%, usage=10746143122, limit=10737418240, percentUsageMinDelta=1%;Parent:Usage(default:store) percentUsage=100%, usage=10746143122, limit=10737418240, percentUsageMinDelta=1%: Persistent store is Full, 100% of 10737418240.

This doesn't make sense to me since my queues all have memory usage at 0..
I monitor the queues with JMX and here is what it is reporting.

"ConsumerCount":2
"DequeueCount":846
"ExpiredCount":0

The output queue can have large objects so I would expect the memoryUsage to be > 0
Here is my destinatio policy
<policyEntry queue=">" producerFlowControl="false" optimizedDispatch="true" maxPageSize="1000">
Can someone explain why the store would fill up and memory usage be 0.. This make no sense to me
