That seems like a really complicated explanation; why would you assume 
that, rather than a fibre problem e.g. bad splice, dirty connector, etc? 
Or even bad SFP+?

I'm unfamiliar with the EX platforms, but it would seem really odd if 
they had this kind of tight inter-port timing constraints just because 
they're in an aggregate; what about diverse fibre paths with radically 
different lengths, which are a common enough config?
