    SubjectZONE_NORMAL exhaustion (dcache slab)
    My big NUMA box went OOM over the weekend and started killing things
    for no good reason (2.5.43-mm2). Probably running some background
    updatedb for locate thing, not doing any real work.

    Big things out of slabinfo:

    ext2_inode_cache 554556 554598 416 61622 61622 1 : 120 60
    dentry_cache 2791320 2791320 160 116305 116305 1 : 248 124

    By my reckoning, that's over 450Mb of dentry cache that's refusing to shrink
    under pressure. ext2_inode_cache ain't exactly anorexic either. Hmmm .....
    Any good ways to debug this?
