Hello!

The cisco_ml2_ci CI has been reconfigured and tested using ci-sandbox repo. 

Patchset: https://review.openstack.org/#/c/192152/ 

The cisco_ml2_ci CI uses my own account in order to  post build status:
"Nikolay Fedotov		10:53 PM
Patch Set 9: Verified+1
Build succeeded.
ml2-nexus SUCCESS in 20m 15s
python27 SUCCESS in 5m 27s (non-voting)"

Additional builds could be found here: http://128.107.233.10:8080/job/ml2-nexus/ 

Could you re-enable "cisco_ml2_ci" account ? 

Thanks
Nikolay

Code where zuul sets EXCEPTION status here: https://github.com/openstack-infra/zuul/blob/master/zuul/launcher/gearman.py#L368-L370 . I could find other places where a job gets EXCEPTION status. I think it failed to add job to Gearman queue because of RAM issue. (Gearman is managed by zuul)

Wonderful, thank you Nidolav for sharing the results of your
investigation. I look forward to hearing when your services are on new
machines.

Something you may want to consider is to have your Jenkins server use
utc time, your zuul server apparently already does. It is up to you and
isn't a requirement, but when sharing logs with others in different
timezones it just makes it easier for folks to understand the chronology
of an event.

I'll wait to hear back from you that your services are moved and running
before I re-enable your account. I will need your assurance that you
will test your system using our ci-sandbox repo prior to resuming
commenting on other repositories.

Thanks for your follow-up,
Anita.
