Ok, a few suggestions:

Do you have any spare SFC's or CSC's?  If so, swap out an SFC, or put  
in the secondary CSC if you have one.

Try forcing a changeover to the standby RP and see if that changes  
anything.  Could even be a problem with the standby.

Reseat all cards (including the CSC and SFCs) and see if that changes  
anything.

What version of IOS?

Here's similar output from our 12012 (which has a bad FastEthernet  
that I know about, that is throwing an SRAM parity error; I just  
haven't replaced it yet):
