Is it possible to configure ActiveMQ (5.8) to purge old messages (messages
that have timed out (ttl) or have been consumed by all subscribers that were
active when a message was posted) from a topic?

We are having an issue where ActiveMQ jams from storing too much data either
in cache or in the db.

I have already set:
expireMessagesPeriod="30000" gcInactiveDestinations="true"
inactiveTimoutBeforeGC="30000"
on all topics in the policyEntry and that works well if there are no active
subscribers but there doesn't appear to be a way of simply removing
redundant messages from a topic with active subscribers.

I have also set:
offlineDurableSubscriberTimeout="120000"
offlineDurableSubscriberTaskSchedule="30000"
schedulePeriodForDestinationPurge="10000"
on the broker to force removal of inactive subscribers.
