possible skipped Queue messages in memory limited configuration with fast consumers
-----------------------------------------------------------------------------------

                 Key: AMQ-3167
                 URL: https://issues.apache.org/jira/browse/AMQ-3167
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.4.2
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.5.0


regression in test from https://issues.apache.org/jira/browse/AMQ-2413 required some investigation.
Symptom was missing messages, turned out to be in the middle of the sequence. Issue with the
priority kahadb cursors and setbatch. Set batch is invoked when the cursor memory is exhausted
such that replay from the store can start at the correct point. If a call to setBatch was
followed by a call to recover when there was still no memory space available, the cursor could
skip the next pending message.
