[ http://issues.apache.org/jira/browse/QPID-7?page=comments#action_12438101 ] Martin Ritchie commented on QPID-7: -----------------------------------
Revision 450401. While the data was being put in tot the unack'd map correctly the sync block did not include the writeFrame call hence the messages could be sent to client out of order. This revision should finally resolve this issue. > Occasionally messages are ack'd more than once > ---------------------------------------------- > > Key: QPID-7 > URL: http://issues.apache.org/jira/browse/QPID-7 > Project: Qpid > Issue Type: Bug > Reporter: Martin Ritchie > > When running a single queue and sending and receiving to that queue in the > same session (Not in a transaction) occasionally the broker appears to get > multiple acks for a given tag. Interestingly when running inside a > transaction this doesn't happen. > 2006-09-21 10:35:24,763 ERROR [pool-10-thread-4] state.AMQStateManager > (AMQStateManager.java:150) - State manager received error notification: > org.apache.qpid.AMQException: Single ack on delivery tag 434 not known for > channel:1 > org.apache.qpid.AMQException: Single ack on delivery tag 434 not known for > channel:1 > at > org.apache.qpid.server.AMQChannel.handleAcknowledgement(AMQChannel.java:550) > at > org.apache.qpid.server.AMQChannel.acknowledgeMessage(AMQChannel.java:492) > at > org.apache.qpid.server.handler.BasicAckMethodHandler.methodReceived(BasicAckMethodHandler.java:50) > at > org.apache.qpid.server.state.AMQStateManager.methodReceived(AMQStateManager.java:165) > at > org.apache.qpid.server.protocol.AMQMinaProtocolSession.methodFrameReceived(AMQMinaProtocolSession.java:358) > at > org.apache.qpid.server.protocol.AMQMinaProtocolSession.dataBlockReceived(AMQMinaProtocolSession.java:326) > at > org.apache.qpid.server.protocol.AMQPFastProtocolHandler.messageReceived(AMQPFastProtocolHandler.java:181) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
