Processor usage drops to zero during non-lin simulations

I've noticed this, and even discussed it with Solidworks engineers.....

 

While performing a "significant" non-linear simulation, occasionally my processor usage will drop to zero, and stay there for minutes at a time, before picking up and resuming the solution calculations.

 

Why is solidworks doing this?   Note that it has nothing to do with the workstation, as I've seen this on multiple machines as well as manufacturers.   Seems like my solutions are taking twice as long as they should because my processor is getting "nap time"  during the solution.   I even have experienced processor usage dropping to zero and staying there indefinately (14+ hours of idle processor, all the while no errors or warnings from the solver.... just sits there and the "elapsed time" in the study solver window continues to tick even though all 8 processors are idle.....

 

Anybody else experience this?   My reseller and solidworks haven't been able to offer any solutions.....
