IRAY sporadically crashes to CPU

in Daz Studio Discussion

I run a GTX 970 and a GTX 780 ti.  I have noticed after multiple renders, it can crash to the CPU for reasons that are unclear.  Can work great for 2 renders, crashes to CPU, I restart DAZ or restart the system and it works fine.  Here's the log file:

I don't know if it happens because I'm running different cards or not.  This one happened when I was just running the 780.  Has anyone else had this happen?  I make sure that the scene size is acceptable for the GPU ram.

    Looks like you may be running out of memory on the cards...what is the amount of memory they have?

    Also, are you closing out and saving each completed render?

    The 780 has 3 gig, the 970 has 4.  I make sure all scenes fit in the smaller memory.

    No, I'm not closing out.  I actually like to use this Batch Rendering plug in:

    https://www.daz3d.com/batch-render-for-daz-studio-4-and-rib

    It might work well for 4-5 scenes, then I have to close Daz and restart it, and it works again for a while.  All of the scenes fit in the GPU RAM as per the Iray memory assistant:

    https://www.daz3d.com/iray-memory-assistant

    It seems like after a render, the RAM sometimes doesn't completely clear.  What I'm looking for is consistency.  For an example, if I was to do an animation of say 150 images, it might have to run a long time.  Is there any way around this?  Very frustrating.

    If you are not saving each one and closing out the render after it's finished, it's still being held in memory.  Iray allows you to resume a render (make minor changes like max time and then continue), but for that to work, it needs to be held in memory and eventually, a few renders or scenes, later, you'll fill up all the video card's memory with 'finished' but held renders.

    One way around it, but you lose the resume ability...render direct to file.  For animation...an image sequence direct to file would be the best way.  Direct to file also works well for batch rendering, too.

    Well, the batch renderer renders direct to file by default.
