TAC suggested it might be:

CSCek26282: MCAST-SP-STDBY-6-GC_LIMIT_EXCEEDED report on standby card

Every single "show" command I've been able to stuff into the EEM applet 
indicates no actual FDB overflow, and the system does have redundant 
sups, so I'm inclined to agree with them.

It's running 12.2(18)SXF2

How does one determine whether the logs refer to the standby sup? If 
it's the -6- in the message, then no - the active sup is the one in slot 
6. If it's the -STDBY- then yes, it is.
