IRAY Errors in logs (video memory issues) seen in DS 4.10 and NOT DS 4.9

in Technical Help (nuts n bolts)

Since installing Daz Studio 4.10 I've noticed the following in my logs.

Context: IRAY render of moderately complex scene (image attached). My rig is a Windows 10 64-bit system with 64 gigs of ram and dual Nvidia GEForce Titan X with 12 gigs VRAM each (max 12 gigs usable).  10.7 gigs in use during the render according to GPU-Z which I always have running to monitor my video cards.  I set DAZ Studio to use CPU and video card 1 only so that I could isolate the work being done and memory used to my IRAY render process.

Every iteration that writes a log entry also writes the following:

2017-10-27 17:06:09.511 WARNING: dzneuraymgr.cpp(307): Iray ERROR - module:category(IRAY:RENDER):   1.6   IRAY   rend error: CUDA device 1 (GeForce GTX TITAN X): May not have enough memory available to execute CUDA kernel (estimated 176.597 MiB).
2017-10-27 17:06:09.512 WARNING: dzneuraymgr.cpp(307): Iray ERROR - module:category(IRAY:RENDER):   1.6   IRAY   rend error: CUDA device 1 (GeForce GTX TITAN X): out of memory (while allocating memory)
2017-10-27 17:06:09.512 WARNING: dzneuraymgr.cpp(307): Iray ERROR - module:category(IRAY:RENDER):   1.6   IRAY   rend error: CUDA device 1 (GeForce GTX TITAN X): Failed to allocate 25.8252 MiB

There's over 1 gig available in the video card, and I've never seen these errors before. I rendered this exact scene yesterday using DAZ Studio 4.9 with no errors or warnings in the logs. 

I'm thinking something was introduced in v4.10 that might have changed the way DAZ Studio communicates with the video cards during IRAY renders. While this is not a show stopper per se, it is alarming because I often render larger scenes and rely on DAZ Studio to communicate effectively with my cards.

Has anyone else seen this?

    Here's the image I rendered:

    Hi, I also noticed some strange entries in the log. When rendering a scene in 4.3 GB on a single 540M/1Gb VRAM video card:

    I would like to see some comments from the developers for this unusual behavior. In previous versions of the DS was clearly written that there is a transition to the CPU render. Also in discussions with others, it turned out that such a picture is observed and they have. If there is a shortage of video memory, writes the same errors to the log and continues (or "continues"?) rendering on the video card with an error.

    Since 4.10 installation, I've gotten crashes in relatively small setups, as well (running two Titan Xp's). Maybe that's my issue!

    I've also been receiving tons of these in the log
