Logs too big for inclusion (the problem was log flooding). Also, they
would be missed by apport-collect because /var had been filled by an
earlier, not necessarily related, problem; the only full copy of the
logs is on a remote syslog server which does not run Ubuntu.

Title:
  Logs flooded with "nfs4_schedule_state_manager: kthread_run: -12"

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  An NFSv4 client running kernel 3.13.0-44-generic #73-Ubuntu (amd64) suddenly started spewing
     nfs4_schedule_state_manager: kthread_run: -12
  log messages at an average rate of 2.65 kHz. It did not stop until I rebooted it.

  At the very least that message needs to be rate-limited. (Doesn't seem
  to be fixed upstream yet.)

  As for the underlying problem, -12 is -ENOMEM. I'm afraid I have no
  idea why the kernel ran out of memory at that point. WIll follow up if
  the problem ever recurs. This bug report is mainly about the lack of
  rate limiting.
