render error...... help me please

[MikeeMax]

I got this error since today when rendering, and i have to give the work to the client tomorrow. IS IT A MATERIAL ERROR ?
I'm lost.
if someone knows wher i could look,

thanks
i use reflextion interpolation (use interpolation checkbox at 20 for most materials. most mats have glosssy ref. ) i use fixed rate at 6. global subd at 2.min samples at 16 noise threshold .005 . i use ambient occlusion.
LC + irr. LC 1000/.02 fixed .04 prefilter 100 use for gloss.

it seems (the render is not finished) this errors appears only when using DR. when using net render with backburner, the render seems to go well (with the exact same scene)
anyway, thats a pain in the ass.....

have anice day
