----------------------------------------------------------------------------------------------------------------------------

                 Key: AMQ-1246
                 URL: https://issues.apache.org/activemq/browse/AMQ-1246
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 4.2.0
         Environment: 4.2-SNAPSHOT (build from 3/26/2007)
            Reporter: Chad Brandon


This error just started occurring after restarting activemq after its memory got fairly high (we've been running our app with this same ActiveMQ 4.2 build for several months without ever seeing this).  It's happening on a persistent topic and doesn't happen after each message is added to the topic but happens every 20 - 30 messages (the occurrence isn't very consistent).
