Byzantine failures perhaps?  If I am getting some corrupt updates, how
confident am I that the rest of the updates are valid?  In any case, it
would appear that the process on the other side has some issues since
theoretically, a malformed update should never (for most values of never) 
arrive.

A combination of bgp dampening and exponential backoff timing for retry on
sessions that were dropped because of an error should take care of the
rest.
