Hi All,

>From 7th December 2018, all of sudden functional-py35 check job is failing
on current master. Earlier this job was failing intermittently (2-3 times
from 100). I have tried to dig into the issue and find out that it is
failing obly for ubuntu and working fine with Fedora, centos etc. Below are
some of the findings:

1. Even if I add failure tests [1] in black-list file every time other
tests reported as failure.
2. When I compared failed tests results [1] with passed tests results [2] I
have found that passing tests shows 'Pass 741 Skip 7' whereas failing tests
shows 'Pass 627 Failure 9 Skip 5' (it does not execute all the tests in
case of failure)
3. I have compared version of subunit, oslo.service, oslo.log, tox with
failed [3] and passed [4] logs and they are same.
4. I came across a bug in cinder [5] which talks about excessive logs might
cause this error and I have tried to ignore the deprecation warning in
tox.ini by adding 'PYTHONWARNINGS=ignore::DeprecationWarning' but it still
shows DeprecationWarning in the logs.
5. I have tried executing tests by setting '--concurrency' to 1 but still
the error persists.
6. Whenver subunit.parser error occurs the tests remains 'inprogress' state
and sometimes time-outs.

I have no clues so far to tackle this issue, kindly provide your inputs for
the same.
