Title:
  p35 jobs are failing with subunit.parser ... FAILED

Status in Glance:
  Triaged
Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Various py35 jobs[1] are failing recently with:

  2019-01-22 00:10:44.708744 | ubuntu-xenial | {0} subunit.parser [0.000360s] ... FAILED
  2019-01-22 00:10:44.708947 | ubuntu-xenial |
  2019-01-22 00:10:44.709000 | ubuntu-xenial | Captured Parser Error:
  2019-01-22 00:10:44.709057 | ubuntu-xenial | ~~~~~~~~~~~~~~~~~~~~~~
  2019-01-22 00:10:44.709122 | ubuntu-xenial |     b'Short read - got 167 bytes, wanted 4263 bytes'

  It seems that when a job fails, the log of the test case that
  triggered the failure is truncated. Also it feels that it is caused by
  extensive logging.

  There was a past cinder bug[2] that was marked fixed after couple of
  logging reduction.

  There was 11 failures in the last 24 hours[3]
