This is your slab-info sorted according to use: bytes used slab ---------- ----- 128,000 filp 128,832 size-64 142,128 vm_area_struct 161,376 size-96 184,320 biovec-(256) 188,160 biovec-64 188,416 pgd 188,416 size-1024 192,000 biovec-128 217,088 size-4096 241,664 size-2048 290,816 size-512 310,464 inode_cache 564,144 radix_tree_node 608,832 ext3_inode_cache 611,520 dentry_cache 688,128 size-8192 917,504 size-32768 1,734,048 buffer_head and that "buffer_head" thing really looks strange. I also wonder what the hell is allocating so many 8kB and 32kB entries. That said, the cumulative slabinfo usage seems to be no more than 8,924,868 bytes, so it doesn't seem to be slab that is the problem. > MemTotal: 125124 kB > MemFree: 1404 kB > Buffers: 19060 kB > Cached: 40484 kB > SwapCached: 33336 kB > Active: 70176 kB > Inactive: 41892 kB "active+inactive" adds up to ~111MB, which together with slab accounts for pretty much all your memory. So there isn't anything unaccounted either. So I suspect it's a balancing issue. Possibly just the slight change in slab balancing to fix the highmem problems. Maybe we shrink slab _too_ aggressively or something.
