Subject [jira] [Created] (AMQ-4092) ConcurrentModificationException when using message groups
Date Thu, 04 Oct 2012 02:57:07 GMT
Ben O'Day created AMQ-4092:
------------------------------

             Summary: ConcurrentModificationException when using message groups
                 Key: AMQ-4092
                 URL: https://issues.apache.org/jira/browse/AMQ-4092
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.6.0
         Environment: ActiveMQ 5.6.0 standalone, kahadb persistence, Spring JMSTemplate producer
(ObjectMessage), Camel 2.9.2 route consumer (AMQ connection pool, vm transport)
            Reporter: Ben O'Day


seeing these WARN messages frequently using consuming (maxConcurrentConsumers=5) from a queue
with the message groups header (JMSXGroupID) set.  If I disable the message groups, these
go away...  

That said, I don't see any specific errors with my application (at this point), just these
messages in my logs.
