xload on Suse 9.0

Hi, When I run xload on my dual Opteron Suse 9.0 64 bit Linux machine, it shows an average of 5 load units when both processors are idle according to gkrellm. I dont need xload, but its upsetting Suns Gridware (www.sun.com/gridware), which is not issueing any jobs to this machine since it thinks its already overloaded. Any thoughts on how I might fix the load calculating mechanism? Thanks, Jeremy.
