Hi,
We're in the process of rolling out Windows 10 64-bit on our workstations and I've been noticing something strange.
Upon completing a V-Ray for Maya render (mayabatch/commandline), the image files are written properly to disk but the mayabatch process hangs and won't exit. Here's where the log ends:
This is a very quick render but the command had been running for 12 hours before we noticed it, and we had to kill the mayabatch process manually.
Since we have multiple V-Ray versions in our pipeline and we just now realized this is happening at least a couple of time a week, it's so far been quite difficult to nail this down to a specific V-Ray version. However, in this particular case V-Ray for Maya 3.05 nightly build 25787 was used. It's quite possible that this issue has appeared with more recent releases but I have yet to have that confirmed.
This seems to happen to Windows 10 machines only. However, these machines can go on render images for many days before the issue is being hit. To further complicate things, the same machine failing to exit properly may re-render the same command without issues and exit properly.
Is this anything you've experienced or had reported from other customers?
