A quick google shows that this is a known problem, but that it should go away if you increase kernel memory. I have done this, but I am still seeing the problem - and not uunder high load either. Is there anything else I can try to mitigate this ? I am running 7.0-RC1 from Jan 3rd at the moment.. cheers, -pcf.
