Just a follow up to this.  First of all, thanks everyone who replied
both in public and private.

After a lot of back and forth, Juniper found in their bug Database
PR575560 - http://bit.ly/s4aCyo (Juniper Login Required)

Summary: "When sending L2 unknown unicast packets @ 90% of linerate,
observing LACP flaps due to LACP PDU missed"

Fixed in 11.2R1 and 11.3R1

Cheers and I hope this helps someone else.
