Soren Hansen, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  AFS gets stuck in an infinite loop, 100% cpu, can't kill -9

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I've seen this a few times, but have not been able to pinpoint the
  exact problem, but I think it's better to have bug report to help
  track it..

  The issue is that in certain cases, I end up with a process that's in
  Running state, seemingly running at 100% in userspace, but can't be
  kill -9'ed. It seems to occur mostly when a process exhausts certain
  ressources..

  I've seen it happen in a VM (using kvm) with 128MB RAM using the
  alternate installer, where localedef ends up in this state (I'm not
  entirely sure, but I suspect that it eats more RAM than is available).
  The server install is unaffected (fewer applications installed, so
  localedef hasn't as much to do, I suppose).

  I've also seen the same behaviour happen while trying to build java
  inside an sbuild where it ran out of disk space. I have a suspicion
  that that particular case might be more related to schroot pulling
  away the snapshot lv from underneat the process, but I figured I'd
  mention it anyway in case they might be related.
