Tiled EXR error

[Morbid Angel]

Colleague of mine has the same error with a Peter Guthrie HDRI. Local render, it renders fine for about most of the 5K render, at 80% done all of a sudden gives him that error. I'm guessing this is network related? All the assets are on the NAS. Only difference that it's not a tiled EXR I guess.

If its not tiled, it will be loaded into ram before render starts, as soon as the first ray intersects the first triangle in the scene where HDRI is traced. So if you are not using any tiled textures then all of them would be loaded into ram ahead of time. If it failes mid render like at 80% the issue is with something else. Perhaps it crashed for a different reason. Could be a build related thing.
