Right, I've been cursory following this thread but I was left with the impression this only occurs on machines where the CPU can go offline, currently the server on which this happened should never offline any of its CPUs since the power management is disabled (though I will have to double check this). On a different note - is there a way to safely reproduce this so I can test the suggested fix by Thomas? > > -Mike >
