I have a pair of 320's and I am getting the same results on the
ps. This machine's been up for about 5573 minutes:

    11:30am  up  3 days,  20:53,  6 users,  Runable processes: 4

The kproc , also PID 514, also started on Dec 31 appears to be
quite CPU intensive:

    USER   PID  PPID   C    STIME    TTY  TIME COMMAND
    root   514     0  76   Dec 31      - 5455:51 kproc

However, 'ps av' reveals that the kproc process is not using any
cpu or memory:

    USER   PID    TTY PGIN  SIZE   RSS  TSIZ    TRS   %CPU %MEM CMD
    root   514      -    0    12     4    0   4194300  0.0%  0% kproc

I'm not real sure of what this indicates...

In my examination of the ps output I did notice this:

    USER   PID    TTY PGIN  SIZE   RSS  TSIZ   TRS   %CPU   %MEM   CMD
    root     0      -    6  4668  7600  0      3800  0.1%    47%   swapper
                                                        Wow ^^^^^^^^^^^^^^

I only have 16M in these machine. Is the swapper really taking up half
of my real memory?
