Public bug reported:
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
