> Key: QPID-4223
> URL: https://issues.apache.org/jira/browse/QPID-4223
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Clustering
> Affects Versions: 0.18
> Reporter: Andy Goldstein
> Assignee: Alan Conway
>
> When testing the new HA in 0.18 (from the svn branch, revision 1370693), I've
> run into a problem where I can't run qpid-cpp-benchmark after I shut down one
> of the backups. Here's the scenario:
> Start 3 brokers (in my test on 3 different hosts) using the following command
> line:
> qpidd --auth no --load-module ha.so --ha-cluster yes --ha-brokers-url <insert
> url here> --ha-replicate all
> Promote 1 of the brokers to primary. Run qpid-cpp-benchmark with the default
> options. The test should succeed and provide results. Next, quit 1 of the 2
> backups. Finally, run qpid-cpp-benchmark again. This time, it hangs.
> Looking at the output of "qpid-stat -q," I see there are some unacked
> messages that have been delivered to the running qpid-receive process.
