    Subject-rc3 leaking NOT BIO [Was: Memory leak in 2.6.11-rc1?]
    Date
    I am running -rc3 on my AMD64 laptop and I noticed it becomes sluggish after 
    use mainly due to growing swap use. It has 768M of RAM and a Gig of swap.
    After following this thread, I started monitoring /proc/slabinfo. It seems
    size-64 is continuously growing and doing a compile run seem to make it grow
    noticeably faster. After a day's uptime size-64 line in /proc/slabinfo looks
    like

    size-64 7216543 7216544 64 61 1 : tunables 120 60 0 :
    slabdata 118304 118304 0

    Since this doesn't seem to bio, I think we have another slab leak somewhere.
    The box recently went OOM during a gcc compile run after I killed the swap.

    Output from free , OOM Killer, and /proc/slabinfo is down below..

    free output -
    total used free shared buffers cached
