Re: Storage utilisation not decreasing when memory utilisation
reaches 70%
Is the advice from https://issues.apache.org/activemq/browse/AMQ-2834
relevant to your use case?

Hello,
I identified the source of problems but don't understand why the
configuration causes them. When I comment out:
<policyEntry queue=">" producerFlowControl="true" memoryLimit="20mb">
(or simply set producerFlowControl to false), then the problems disappear.
Can't be there some problem with the producer flow control?

I think you forgot to attach your activemq.xml file... or I am totally
blind ?
