Bug#808479: linux-image-4.3.0-0.bpo.1-amd64: Confirmation of this bug; bug due to climbing memory usage

Version: 4.3.3-7~bpo8+1
Followup-For: Bug #808479

Dear Maintainer,

I can also confirm this bug on an Inspiron 530 w/ 2GB RAM. On this computer, it
takes about 15hrs. to crash the computer. The memory usage climbs up to that
point, not due to any usage on the part of applications. The kernel keeps
claiming more and more memory until the OOM killer is invoked and kills all
applications. The applications meanwhile remain constant in memory usage. I
have kern.log backups I could attach, but all they show is the OOM killer's
invocation.

The issue is also clearly in the kernel, because just like the original
reporter, a revert (to 3.16) fixed the problem. I will try to see what some of
the possible culprits in the changelog for the kernel are. In the meantime, we
can use either 3.16 or 4.2.

This bug might also be good to have marked important, as it makes the
kernel nearly unusable in some cases, and it is a fairly big bug. I also
would say it is probably upstream, although that can't be said for certain
at this point, I don't think.
