>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Broker
>    Affects Versions: qpid-java-6.0
>            Reporter: Alex Rudyy
>            Assignee: Keith Wall
>             Fix For: qpid-java-7.0.0
>
>
> Direct memory QpidByteBuffer in MessageConverter_to_1_0#convertServerMessage(...) is not disposed programmatically. We rely on GC to release it from memory when it became unused. There is a risk that when such QpidByteBuffers are not "garbage collected" soon enough Broker might run out of direct memory on heavy loads.
> Currently a user who relies heavily of message conversion with high rates of message flow, may see an OOM direct.
