Hello:
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,
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:
