Bug Description
Seen here:
The test times out and the underlying issue seems to be an InterfaceError from pymysql:

The thread switch issue could be related to bug 1793364.
The funny thing about this is it started spiking since April 1 when this merged:

And it predominantly shows up in the limestone-regionone nodes, I'm not sure why.
The change above that merged on 4/1 also removed skipsdist=True from nova's tox.ini so I'm wondering if there is something on the bionic images in those limestone nodes that causes weird issues.
I noticed in the job that failed that tox is 3.8.4 and in another job that passed tox was 3.8.1, but looking at:

I'm not seeing anything obvious about a behavior change for python 3.6 jobs.
Changed in nova: | |
importance: | Medium → High |
This would also help to explain why we've been seeing a spike in unit test job timeouts for nova recently because these tests hit that thread switch and then timeout.
