[Bug 1768077] [NEW] intermittent functional test failures related to scrubber

 

Public bug reported:

I'm not completely sure that the scrubber tests are the culprit, but
they seem to be a common factor.

We're seeing different failures in the functional (py27) tests and the
functional-py35 tests.

(1) py27
"AssertionError: unexpected error occurred in glance-scrubber" happening in wait_for_scrubber_shutdown

Observed on:
- https://review.openstack.org/#/c/564077
- https://review.openstack.org/#/c/564883

See http://paste.openstack.org/show/720153/ (not sure how long the logs
will be kept).


(2) py35
This one is trickier because the failure is causing the subunit parser to crash during test runs, so there are several tests failing, but it looks like the scrubber tests are the constant factor.

Observed on:
- https://review.openstack.org/#/c/564649/
- https://review.openstack.org/#/c/564077/
- https://review.openstack.org/#/c/554174/

See http://paste.openstack.org/show/720155/ for list of tests failing when this happens.
