FilePendingMessageCursor isFull reports full in error when temp store is full,
even if not needing the temp store
-----------------------------------------------------------------------------------------------------------------
Key: AMQ-3314
URL: https://issues.apache.org/jira/browse/AMQ-3314
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.5.0
Reporter: Gary Tully
Assignee: Gary Tully
With slow queue consumers of non persistent messages the temp store can be
filled and producers blocked. The default cursor for non persistent is a
fileCursor.
However topic subs with a pending message limit strategy also use a cursor for
pending messages. If there is sufficient memory resources, the topic consumers
should be able to operate without recourse to the temp store. At the moment
this is not the case, as the check to isFull reports true in error (based on
the status of the temp store)
It should only report full if its memory is exhausted || it is spooling to disk
AND the temp store is exhausted.
