mdrozdziel, 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 Precise via
http://releases.ubuntu.com/precise/ ?

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-rc5

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:
  Fresh install of Ubuntu 10.10 x86_64 2.6.35-28-server leaks memory
  over time.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have Ubuntu 10.10 x86_64 2.6.35-28 installed on two mirror machines.
  Kernel processes are slowly consuming whole available memory over
  time. Tooks around 10 days to eat up 4GB which leads to obvious total
  crash.

  On the pastie below, you can check how does the slab info looks like
  around 24 hours prior to coming crash.

  http://pastie.org/private/lmx2xhijugfi8zkic4cpsa

  Its always kmalloc-192 and kmalloc-32 which are leaking the memory
  with the mutual proportion 6:1 (192:32). I am not really sure where to
  go from that point. Is there any other possible way to diagnose to
  cause a bit deeper?

  I found out some posts from people with quite similiar issue on pretty
  much same hardware. The proposed solution was to disable acpi and apm,
  but it doesn't solved the issue on my boxes.

  Any ideas much appreciated.

  Hardware is from HP (DL360G5).

  Debian 6 works great on the same hardware, as do Ubuntu 10.10 on other
  boxes. This has to be on the edge of hardware and software. No idea
  where to go from there. System is pretty much unusable.

  I posted the same problem on stackoverflow
