:I wrote about this back in November, but enabling sendfile in apache
:seems to make it use more and more cpu as the server runs.  Right now
:I've been running the server for about an hour, and I have a load of
:about 20.  If I disable sendfile in apache, it seems to work fine.  If
:I run ps, it says those processes are in a 'RL' state.  Is it normal
:for sendfile to use this much cpu?

:Of course I'm willing to provide an info required to figure this out.

    It sure isn't.  Do a ktrace -p <pid> of one of the apache's while it
    is in that state, for a few seconds (terminate it with ktrace -C).
