----------------------
Priority: Critical (was: Major)

> ------------------------------------------------

> Key: QPID-6676
> URL: https://issues.apache.org/jira/browse/QPID-6676
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Clustering
> Affects Versions: 0.32, qpid-cpp-0.34
> Environment: CentOS6.5 X86_64
> Reporter: 李翰林
> Assignee: Alan Conway
> Priority: Critical

> I build QPID 0.32 C++ broker with HA module on CentOS6.5 and run a cluster of
> 2 nodes with --ha-replicate=all, Then send messages using QPID Messaging API
> continuously with protocol AMQP0-10 and I meet a strange problem,If I purge
> all of messages in a queue and continue to send messages,The throughput drop
> sharply. And the same problem seen on QPID 0.34
> Steps to reproduce:
> 1:
> qpid-config add exchange direct testHA.exchange
> qpid-config add queue testHA.queue --max-queue-size 1048576000
> qpid-config bind testHA.exchange testHA.queue testHA.binding
> 2:
> Run "qpid-queue-stats -f testHA.queue" on a console
> 3:
> Send 100000 messages to testHA.exchange with routingkey testHA.binding
> 4:
> Purge queue use the QPID manager tool (qpid-tool)
> 5:
> Repeat step 3
> get the output from step 2:
> Queue Name Sec Depth Enq Rate Deq Rate
