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
