I have setup a transactional message listener in Spring, using ActiveMQ and Atomikos for JTA. ActiveMQ uses MySQL for persistency, no journaling is done. I noticed that the ID field in the activemq_msgs table increases for no apparent reason, without messages being posted on the queues. I enabled debug logging for ActiveMQ and noticed this:

Any idea what is causing this?
