             Summary: Producing application using a connection per message pattern for small long lived messages may crash the Broker
                 Key: QPID-7754
                 URL: https://issues.apache.org/jira/browse/QPID-7754
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: qpid-java-6.1, qpid-java-6.0
            Reporter: Keith Wall


A consequence of the direct buffer strategy currently employed by the Broker is that if a producing application uses a new connection per message, then each message holds an additional {{256K - payload/header size}} bytes of direct memory unused until the message is consumed.   The worst case is for small messages, where the waste is at its most.
