Interesting, I saw this continually happen every few minutes for just
over an hour about a week ago for no explainable reason, and I too
just recently upgraded to 6.3R1.3.  The DR is an M10, and there are
two Nortel Passport 8600 routers, one of which is the BDR.  There were
no link status changes or errors on the links.  All the routers logged
the same error messages "NBR declared dead on inactivity".
