Re: 119.5% CPU load

[Ken Brownfield <brownfld@irridia.com>]

Heh, that's nothing.  I see this all the time (I just chose a random
machine and voila):

  7:35am  up 172 days,  7:29,  1 user,  load average: 8.76, 9.69, 10.87
126 processes: 117 sleeping, 9 running, 0 zombie, 0 stopped
CPU states: 38.9% user, 18.9% system, 42.1% nice, 421902.3% idle
Mem:   517192K av,  514040K used,    3152K free,   78564K shrd,   84884K buff
Swap: 1025016K av,    4380K used, 1020636K free                  255572K cached

I've always assumed it's a 'top' precision issue, but I think I've only
seen this on 2.2 now that I think about it.
