Strange render times

[John Bigboote]

Anyone else get these unusual render frames... I left my PC(nothing else running) to render overnight and saw I have some frames that take unusually long... 5 hours 34 minutes when the frame before was 2min20??? A:M V18.0G 64 bit... using SSS hair.

I'd be curious to repeat that render and see if the same frames do it again.
