of-flow: whole karaf down while configuring 100k flows

odl: https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/distribution-karaf/0.3.0-SNAPSHOT//distribution-karaf-0.3.0-20150217.002825-479.tar.gz

configured features: odl-openflowplugin-all (IMDS used, not clustered DS)

max java heap was set to 4G, perm size to 1G

To running odl i connected 250 switches with mininet and start configuring 100k flows. The task was not finished because karaf died. When i logged on the testing machine, karaf process (java) was not present there.

The log file is taken from the job:
http://sn-bldsg.cisco.com/jenkins/job/test-openflow-performance-single-master/179/

To configure you can use scripts from
integration/test/tools/odl-mdsal-clustering-tests/clustering-performance-test
e.g. flow_add_delete_test.py --host <host> --threads 5 --flows 20000 --auth

The log file is present at

It has nearly 4G.
