-----------------------------------
This seems to be sorted now if you want to resolve it.
> FilePendingMessageCursor can retain memory after flush to disk till next
> reset via internal iterator

> Key: AMQ-4248
> URL: https://issues.apache.org/jira/browse/AMQ-4248
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.6.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Labels: cursor, memory, oom
> Fix For: 5.8.0
>
>
> the contract for cursor iteration is to call
> {code}reset,next...,release{code}
> If the cursor is flushed on add, the memory list is cleared but the iterator
> is still referencing the list, which causes memory bloat. It will be released
> on the next call to reset (which may take some time depending on consumer
> activity), but it should be gone after the previous call to release.
