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
