I noticed that 0.18 Java Broker does not appear to be persisting message
to the derby store. Running tests to verify memory thresholds in a
disaster recovery situation. Had 100k+ messages on a durable queue with
no consumers. When I bounced QPID, the memory usage was almost none and
noticed the log wasn't recovering any messages:
QPID2013-03-04 09:19:03,789 INFO [main] (Log4jMessageLogger.java:73) -
[Broker] [vh(/edex)/ms(DerbyMessageStore)] TXN-1004 : Recovery Start

messages for queue external.dropbox
2013-03-04 09:19:03,809 INFO [main] (Log4jMessageLogger.java:73) -

2013-03-04 09:19:03,817 INFO [main] (Log4jMessageLogger.java:73) -
[Broker] [vh(/edex)/ms(DerbyMessageStore)] TXN-1006 : Recovery Complete
Dug a little more and none of my durable queues are persisting.
Anything I'm missing? I do have the store configured in my
virtualhosts.xml:
<store>
<class>org.apache.qpid.server.store.derby.DerbyMessageStore</class>
<environment-path>${QPID_WORK}/messageStore</environment-path>
</store>
Here is a sample from the rest interface:
