You're right, the usage is unclear.  As far as we can tell, packet
traffic through the router triggered the crash. This does not appear
to have been caused by punt packets to the CPU. However, we have no
details. All that we know for sure is that both routers crashed at the
same time.

We don't have any detailed info on the packet contents or quantity. 

I agree that the vendor should take action to protect their customers
from this kind of exposure.
