I've noticed an upstream server I slave from is being suspiciously consistent in the number of records it sends per IXFR (86,450 plus or minus ~10 records).  The upstream server is part of an appliance, but fingerprints as BIND 9.2.3rc1 -- 9.4.0a0.  

Nevermind.. I spoke too soon.  It turns out the appliance in question is not actually doing IXFRs.  I should have checked out the zone size in the first place.
