Functional reload tests are flakey

[Ian Cordasco]

http://logs.openstack.org/periodic-stable/periodic-glance-python27-db-newton/95226d2/testr_results.html.gz is an example of a periodic gate failure in Glance's functional test suite, specifically: glance.tests.functional.test_reload.TestReload.test_reload

This test fails occasionally trying to assert that new log files are created. At the moment, it's unclear exactly what the root cause of this flakey test is. The test seems to work just fine locally, so reproducing it may be time consume. For others, the complete output from the test failure is:

    Traceback (most recent call last):
      File "glance/tests/functional/test_reload.py", line 251, in test_reload
        for _ in self.ticker(msg):
      File "glance/tests/functional/test_reload.py", line 72, in ticker
        self.fail(message)
      File "/home/jenkins/workspace/periodic-glance-python27-db-newton/.tox/py27/local/lib/python2.7/site-packages/unittest2/case.py", line 690, in fail
        raise self.failureException(msg)
    AssertionError: No new log file created

And the api log information has been reproduced here: http://paste.openstack.org/show/589157/

Tomislav on the mailing list has had no luck reproducing this. For now, I'm going to start tracking the locations where this fails to see if we can narrow it down to a provider and/or region.

This particular failure happened on:

    ubuntu-xenial-osic-cloud1-disk-5331494

Have not heard of this coming up recently.
