            <title>[CONTROLLER-829] Clustering : Datastore causes Out Of Memory</title>
                <link>https://jira.opendaylight.org/browse/CONTROLLER-829</link>
                <project id="10113" key="CONTROLLER">controller</project>
                    <description>&lt;p&gt;To reproduce,&lt;/p&gt;

&lt;p&gt;1. Build the OpenFlowPlugin Karaf distribution&lt;br/&gt;
2. Run the controller with the following options&lt;br/&gt;
JAVA_MAX_MEM=4G JAVA_MAX_PERM_MEM=512m ./karaf&lt;br/&gt;
3. Install the odl-mdsal-clustering feature, also install jolokia&lt;br/&gt;
4. Run the attached script with the following options&lt;br/&gt;
 /usr/local/bin/python flow_config_perf.py --nflows 500 --nthreads=5 --ncycles 60&lt;/p&gt;

&lt;p&gt;At around 125,000 Transactions the controller will run out of memory&lt;/p&gt;</description>
