    Same here.. After upgrading to 2.6.8-rc2 the OOM-killer is going crazy.
    It's particularly angry at the backup client 'dsmc' (from Tivoli Storage
    Manager). I'm monitoring its usage with 'top', and 'dsmc' is not using
    more than ~150MB in either size or RSS when the OOM-killer takes it down.

    The 'dsmc'-process is reporting that it's processed 2,719,000 files, and
    transfered 164.34 MB when it gets killed. i.e. it's traversed a lot of
    files, but only read about 164 MB data, so it shouldn't have filled up any
    buffer cache...

    The system still has lots of free memory (~900 MB), and also 2 GB of
    unused swap. Actually there's 0K used swap..??

    I've tried turning on vm.overcommit_memory, but it had no effect. Also
    tried changing the swappiness both up to 90% and down to 10%, but it
    never uses any swap.. ???

    BTW: I had no OOM-killer problems on 2.6.7.
