MRL Mid Length Hair won't render

HI all,
I have MRL Mid Length Hair and whenever I include it into a scene lately, it will cause the scene to not render due to supposedly running out of video memor (I have CPU fallback disabled.). I have 8GB memory of video ram and I am certain I am not running out (some of the scenes aren't complex enough to even come close to causing that). Here is the logs from a recent complex scene that won't render in GPU:

Mind you I can render other scenes just fine unless they include this hair. I also seem to be having the same problem with the Minimilistic Autumn boots. I'm not so cecerned about those though. I need this hair. It used to render, I don't know what's changed (the hair might have been updated).

dForce hair can use a lot of memory, and apaprently it is going over the limits for your hardware. Chevvybabe has a thread on optimising dForce hair https://www.daz3d.com/forums/discussion/380281/chevybabe-s-dforce-sbh-hair-thread#latest
I highly doubt that's really the case. I have 32 GB of system ram, 8 gb of graphics ram. The logs aren't reporting it's using all that much. And as I've mentioned before I've test rendered this scene before. I'm worried the hair has some type of memory leak. I can get the hair to render on less complex scenes but my video ram is getting 80% + full and Daz isn't reporting it's using that much geometry memory or textures. I might be stuck contacting technical support because of this. I don't look forward to that.
