High Load Average

hi, i am experiencing a problem with very high Load Average, and do not get much wiser from looking under Process Manager. It is only one command, called "id" which takes approx. 500 - 600% of CPU.

Pid	Owner	Priority	CPU %	Memory %	Command
20556 (Trace) (Kill)	root	0	606.86	0.01	ls

Each time i Kill it, it just pops right back up. Any clue what this could be?
