Hi all,

 

     I have recently built FreeBSD 9.3 (i386) from the ground up (making our
next gen server build). 

Once complete I have been allowing it to run under no load, and have noticed
that the load averages

Hovering around 0.40 - 0.50 (see below).

     I have TERM'd and killed just about everything and the usage remains. I
have never seen any other server do

This with any other build. Is there something new in 9.x that might be
causing this? I have servers running 8.0

With lots of software running that is not this high.

    I am not at all concerned about the hardware as it was an active server
with no issues, and the system compiled

without any issues.
