Render Queue crashes out after a couple scenes with QWidget failure to create window messages

AndyAkins

When I run the new Render Queue, it processes a couple files and then my log fills up with:

[ERROR] :: QWidget::create: Failed to create window (The current process has used all of its system allowance of handles for Window Manager objects.)

And eventually DAZ crashes.

I've deleted some old plugins I had but never used (or were replaced by the new version), but it still is happening.

Curious if anyone else has seen this, or if anyone has any ideas on what could be going on.

I just started having this problem as well. It isn't just Render Queue either, it also happens after I open about 6 scenes in a session manually.

From my experience, there is memory leak in DAZ 4.23.0.1 with NVIDIA driver 565.90 when doing IRay render. I have 24 GB VRAM and I have to restart DAZ after about 300 rendered frames. Each IRay render eats a bit of VRAM and the VRAM is totaly full after about 300 frames. I think it is also your the problem.

It's possible but the error message is a Qt error "Failed to create window", that could be a side effect of course but it does not sound like GPU related problem, on the other hand the only way to fail to create a window on Windows from one time to another is usually that you run out of user memory, there is a limit on the number of user objects that can be created set in the registry, the only time that happens is normally that you have a memory leak that does not delete old user objects somewhere, now as said, this can be a side effect and not the real problem.
