I don't have info about microcode update, only a note from dell support which said that it's correcting
instability on vmware. (So I don't known for kvm)

I'm going to implement serial output over the dell idrac.

Could this, given the high load, be caused by a race condition which is 
solved in the new microcode?

If you have IPMI on the nodes you should also be able to monitor 
further than on the default console.
