Hi All,<br>
<br>
As many of you have noticed the gate has been in very bad shape over the<br>
past few days. Here is a list of some of the top open bugs (without pending<br>
patches, and many recent hits) that we are hitting. Gate won't be stable,<br>
and it will be hard to get your code merged, until we fix these bugs.<br>
<br>
1) <a href="https://bugs.launchpad.net/bugs/1251920" target="_blank">https://bugs.launchpad.net/<u></u>bugs/1251920</a><br>

<br>
Can we know the frequency of each failure?<br>
I'm trying 1251920 and putting the investigation tempest patch.<br>
<a href="https://review.openstack.org/#/c/57193/" target="_blank">https://review.openstack.org/#<u></u>/c/57193/</a><br>
<br>
The patch can avoid this problem 4 times, but I am not sure this is<br>
worth or not.<br>
<br>
<br>
Thanks<br>

Joe seemed to be on the same track with<br>
<a href="https://review.openstack.org/#/q/status:open+project:openstack/tempest+branch:master+topic:57578,n,z" target="_blank">https://review.openstack.org/#<u></u>/q/status:open+project:<u></u>openstack/tempest+branch:<u></u>master+topic:57578,n,z</a><br>
but went far enough to revert the change that introduced that test. A<br>
couple people were going to keep hitting those changes to run them<br>
through more tests and see if 1251920 goes away.<br>
<br>
I don't quite understand why this test is problematic (Joe indicated<br>
it went in at about the time 1251920 became a problem). I would be<br>
very interested in finding out why this caused a problem.<br>
<br>
You can see frequencies for bugs with known signatures at<br>
<a href="http://status.openstack.org/elastic-recheck/" target="_blank">http://status.openstack.org/<u></u>elastic-recheck/</a><br>
<br>
Hope this helps.<br>

<br></blockquote><div><br>That has been really useful. I think having a known page we can go to when the gate<br>gets in really poor shape would be very handy (or maybe just put it in the various irc channel topics).<br>
<br></div><div>Also does it make sense to ask people to stop doing rechecks as well when the gate is stuck to<br></div><div>allow those who are putting through debugging patches quicker feedback?<br></div><div> <br></div>
