Houdini Crash when modifying/rendering fur

[joaquin0850]

Im trying to render a fur project using arnold, but im having a 'fatal error segmetation fault'  randomly when playing with the hair generator or rendering, I am unable to render  more than 10 frames, sometimes not even one...

 

 I simulated my guides with vellum, cache them, and did the usual clump, frizz process, merge every groom node together in my render geometry node.. everthying  is moving correctly following the simulated guides, i also added rest position to the skin and guides but still get the error, what am i doing wrong?

 

 

Thanks in advance
