Hi,

I have an annoying slab leak on my kernel.  Every day, I lose about
50Megs of memory to the leak.  It seems to be related to disk
accesses, because the count only goes up noticeable around 4:00am when
the system locate utility runs.

I can tell there is a leak because /proc/slabinfo shows "size-128"
growing continuously.  For example, it currently reads:

size-128          4086041 4106550    128   30    1 : tunables  120   60    8 : slabdata 136885 136885      0

The machine is a vanilla lkml kernel:

Linux double 2.6.15 #1 SMP Wed Jan 4 23:13:51 EST 2006 x86_64 x86_64 x86_64 GNU/Linux

I've noticed this bug on a 2.6.14 kernel also.  This machine is using
libata (sata_uli) along with reiserfs, ext3, and lvm.  I'm interested
in finding ways of diagnosing this problem.  I can provide more
information on demand.  Please CC me on any replies.

Thanks,
-Kevin
