 Description   

Tested the Legacy Netvirt in stable/Boron

a. 3node ODL feature: odl-ovsdd-openstack

b. Used 3 Openstack nodes

c. After stacking successfully, checked the flow entires in all openstack nodes

expectation: initial pipeline flows to be installed

REsult: In 2nodes, the flows were installed successfully, it failed in 1 openstack node.

Checked the karaf .log and saw the below ERROR getting repeated for a long time

---------------END---------------

After sometime some flow entries were installed, but stil lthe initial pipeline flows were missing.

Attached the logs from all three ODL

Error is found in ODL3 log and once in ODL1 log.

Testing again with latest image.

after this patch got merged : https://git.opendaylight.org/gerrit/#/c/44476/1

Comment by Andrej Leitner [ 25/Aug/16 ]

Hi Venkat,
we didn't find this issue recently. Could you please retest it with actual codebase? (master or boron, it could be one-to-one actually)

Thanks.

Comment by Andrej Leitner [ 13/Sep/16 ]

No activity here for almost 3 weeks, decreasing to normal.
Venkatrangan, did you have a chance to test it with the latest build?

Comment by Karthikeyan [ 19/Sep/16 ]

Tested this with the following distribution
https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/distribution-karaf/0.5.0-SNAPSHOT/distribution-karaf-0.5.0-20160913.171011-4892.tar.gz

The bug is not reproduced.
After stacking, checked the initial pipeline flows entries in all openstack nodes.Flows are installed properly.

Comment by Andrej Leitner [ 19/Sep/16 ]

If there is not really the problem or was fixed on the way, please close the bug.

Comment by Venkatrangan Govindarajan [ 20/Sep/16 ]
