HtoA CRASHED in memcpy

[contactHPG7V]

Hey guys,

I'm pulling my hair for some time now. IPR renders all of the frames in the range, only when I write to disc it writes the first frame and then cancels after with following error at the end of the log: (I've attached the whole log to this post)

Does anyone know what is happening here?

i fixed this by turning of "preserve layer name". that seems to not work if you write a regular and a deepexr in the same arnold rop.

still not sure what caused this, because after restarting houdini everything works. i can now even render crpyto, deep and denoise variances for light aovs in the same rop when i put out deep and crypto to a seperate files. works even with mixing 16 bit and 32 bit outputs. nice!
