             Summary: Log subscription state change message (SUB-1003) only when a subscription has been suspended for an unusally long period of time
                 Key: QPID-6575
                 URL: https://issues.apache.org/jira/browse/QPID-6575
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
            Reporter: Keith Wall
             Fix For: 6.0 [Java]


SUB-1003 is logged currently whenever a subscription changes state i.e. as the client session/consumer is able to accept more messages.  With some use-cases (low prefetch) and some messaging stacks (Sping's DMLC) this can be very frequent.   Indeed, with Spring in certain configurations, this will lead to a pair of messages per message.  For this reason,  we turn off SUB-1003 in the log4j configuration.   In v6, we have killed the log4j configuration so SUB-1003 is being logged again.
