Agg rendering complexity exceeded

Recently, I've regularly encountered the error of "Agg rendering complexity exceeded" when attempting to plot, despite the amount of data being (I believe) reasonably sized.  After some trouble-shooting, I'm realizing that it's specific to certain Msids (PFDM202T and PLINE08T), although I don't know why.  

sample code:
x = fetch.Msidset(['PFDM201T','PFDM202T'],'2006:001')  #same sample rate
x['PFDM201T'].plot() #works fine
x['PFDM202T'].plot() #always crashes 

Note that each is only ~10 million points, which per the Eng Archive website's "rule of thumb" should be okay.

I was unable to recreate the PLINE08T error today...
