>Description:
This is a Proliant 380 G5, running the 64-bit FreeBSD 7.0-RELEASE.

Top's output seems like total nonsense.  The server is not deployed yet.  So I ran rsync to see what strangeness might occur.  Only rsync is really active.

Here's a snippet of top's output:

last pid:  7591;  load averages:  7.70,  8.78,  9.87    up 0+09:14:46  02:34:03
61 processes:  1 running, 59 sleeping, 1 stopped
CPU states:  1.1% user,  0.0% nice, 34.4% system,  3.1% interrupt, 61.4% idle
Mem: 208M Active, 7031M Inact, 377M Wired, 257M Cache, 214M Buf, 40M Free
Swap: 8192M Total, 4K Used, 8192M Free
