[c-nsp] 3745 router crash

[Robert Johnson]

I have a 3745 router with 256D, a NM-1FE-FX in slot 0, and a NM-2FE2W
in slot 1. IOS 12.4(25a).

On Wednesday the router locked hard and was unresponsive from console,
etc. Power cycle brought it back up. This morning the router crashed,
but this time came up on its own. I'm not finding much public
information on the below "address parity error", and I'm not familiar
enough with this platform to be able to tell whether this is a
software bug, bad NM, etc. Any suggestions would be greatly
appreciated.

Here are the interesting tidbits:
