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

Status in “linux” package in Ubuntu:
  Expired

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.

  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
