Hello!

I was running a single instance of SETI@Home, when I observed the load
of 2. I stopped seti and the load went down to one. It stays there for
about 20 hours already. The machine is idle:

last pid:  1886;  load averages:  1.00,  1.00,  1.00    up 0+20:36:36  10:33:11
16 processes:  1 running, 15 sleeping
CPU states:  0.4% user,  0.0% nice,  0.0% system,  0.0% interrupt, 99.6% idle
Mem: 7136K Active, 20M Inact, 9024K Wired, 56K Cache, 22M Buf, 88M Free
Swap: 256M Total, 256M Free

  PID USERNAME PRI NICE  SIZE    RES STATE    TIME   WCPU    CPU COMMAND

This is a 4.3-beta:
	FreeBSD 4.3-BETA #0: Tue Mar  7 22:58:18 EST 2000
on a single Pentium-II 266MHz with  128Mb of RAM. The unusual (somewhat)
things are: no video card, two  Promise-66 IDE controllers, while the on
board IDE  is disabled  (they are  WDMA2 only).  I think,  this happened
before to someone, but I could not find the thread. Any clues? Thanks,

	-mi
