Comment 5 for bug 1514935

It's pretty clear that 243808 is the fix. If you look back on the Jenkins fails for https://review.openstack.org/#/c/164880/ this was actually triggered in Patch Set 33: http://logs.openstack.org/80/164880/33/gate/gate-tempest-dsvm-neutron-full/56c541a/console.html.gz#_2015-10-21_19_57_34_141

Which blocked it from landing in the gate.

Then YAMAMOTO Takashi did a recheck to rerun the tests to land it.

It failed again on check - http://logs.openstack.org/80/164880/33/check/gate-tempest-dsvm-neutron-full/4e68240/console.html.gz#_2015-10-22_02_12_35_331

Rosella followed up with a correct observation that the fails might have been related to her patch and put it into workflow-1 state.

Patch 34 was pushed, and got lucky and passed check and was approved to gate.

Unfortunately at the 35% race rate, it means this was just litterally winning a coin flip. We got the 42% chance that it would pass both times (0.65^2).

Probably in future it would be better to run some manual rechecks on a patch like this preemptively to attempt to trigger the failure when it's been known to trip things in the past.
