	I've been getting odd behaviour with SGE 6.0u6 on SUSE 10 where it's 
reporting my dual x64 Intel system load is 4, 6, 10 even as high as 12, and 
thus not sending jobs to the slots till it "cools down".  Now that you 
mention this, I checked uptime and indeed, I'm getting results like:

3:29pm  up 35 days  2:58,  5 users,  load average: 8.48, 4.75, 5.73

	and I've seen that average middle number match what SGE says.  I assume this 
means SGE is determining this(fairly enough) by querying uptime or a similar 
call.  Anyone have any thoughts why uptime would be reporting such high 
numbers?  I'm guessing it's because it's x64, but it seems like a bug 
regardless.  Any thoughts offhand on a workaround?
