That appears to be nmon failing, probably picking up a stale pointer or
following some bunny trail. It's something to pick up with Nigel. It does
not directly contribute to CP overhead, but it's possible that the recovery
consumes good CPU resources that make the guest compete harder for CPU
resources to get the real work done, and find more contention when getting
beyond allocated capacity.
