[Paul Stewart]

Crap.. I was afraid you'd say that....;)  Thanks for the input... We're
going to try a reload overnight just to see if the errors come right
back or not...

I'd open a TAC case - personally, I'd probably request an RMA on this

message, I expect it is legitimately failing to write data successfully
to the FIB SSRAM.
