I'm also seeing the load average problem on my system.
Same here. I think the culprit is the kxbwatch kernel thread, which ps
shows as being in the "D" (uninterruptible sleep) state most of the time
on my system. My understanding of load average computation is that "D"
processes count as running (typically, they correspond to a running
process blocked on I/O).
If this is the case, then the load average of 1.00 should be harmless,
though it would be nice to get the xenbus thread to use a normal sleep
so it doesn't skew the load average.
One thing is that 1.00 load avarage when idle, but if it's the kxbwatch,
then does it escalate when the systems are actually doing something?
If not, it shouldn't do much harm, right?
