Description Daniel Mellado 2015-11-18 11:53:46 UTC

Description of problem:

While running neutron tempest tests in rhos, there's an occasional server fault error which makes the test fail. Restarting the neutron-server in order to enable debug seems to fix the issue, so this could be related to a race condition on the ddbb.


Version-Release number of selected component (if applicable):


How reproducible:

Run python -m testtools.run tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_subnet_details

-eventually- the test would fail and you'll get a server fault as a trace

Actual results:

TRACE neutron.api.v2.resource     "This result object does not return rows. "
TRACE neutron.api.v2.resource DBError: This result object does not return rows. It has been closed automatically.


Expected results:

The test to pass


Additional info:
Might be related to the launchpad bug attached

Could you provide a more detailed trace (tempest logs + neutron server logs?)

Comment 2 Daniel Mellado 2015-12-15 14:04:10 UTC

After running it more than 20 times with the latest puddle I'm unable to reproduce the bug to post the logs, so I'll be closing it for now
