    No idea. :) Belive me, next reboot that's one patch that's going in
    fast.

    news 8869 2.9 5.6 12568 10840 ? S Feb 21 296:18 /usr/sbin/innd
    root 1 7.3 0.0 804 48 ? S Feb 20 851:32 init [3]

    Init has used nearly 3 times as much CPU as innd. And that innd is
    taking a full feed! As far as I can see, it's because init is
    constantly sync()'ing producing constant runs through the disk queue.

    Michael.
