[c-nsp] High process CPU on 3750

[Ed Butler - RapidSwitch]

We've got a stack of 3750s that are currently showing high process usage on
the CPU.

This is showing as process utilisation on the switch, but I can't see a
process that actually accounts for it in the list.

There is about 30-35% of the CPU that has vanished and it's not clear where.
