[f-nsp] debugging restarts

[Joseph Hardeman]

Tomek

I did both of these and I have also cleared the dumps and am waiting for 
the next restart.

How do I debug the dm save output?  Is there a program or guide that 
will help me understand what it means and what is causing the restarts?

Thanks

Joe
