[j-nsp] SNMP stat from PE-4GE-TYPE1-SFP-IQ2

Hi all,
I'm having some trouble graphing traffic stats from a PE-4GE-TYPE1-SFP-IQ2 from multiple network monitoring boxes.  The issue seems to be that when the traffic for one of the ports on the PIC reaches > ~200Mb/s the graphs become jagged.  I am using SNMPv2, as well as 64-bit counters.  Stats on other non-IQ2 PICs seem to work fine at >200M.  This one particular interface has MAC accounting enabled, but I doubt that's the problem.  I'm on an M7i running 8.5R1.13.

Has anyone else come across this?  I looked through the JUNOS bugs and couldn't really find anything relevant.  I'm pretty sure that it's not my NMS or how I'm graphing, as I have three different sources (MRTG, Cacti, and Solarwinds Orion) currently graphing the interface and all show the same jagged results.
