Public bug reported:
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.
