VRay Standalone Stops Before Completion

[peepo]

Im doing pretty standard renders 8000 x 5000 px @ 300 dpi) on a 4GHz Mac running Sierra 10.12.6 with 32 Gb of RAM. Im launching VRay standalone from MODO 11.1v1 and using VRay 3.5.

A couple of times of different projects, the render stops prematurely with a the last few lines:

...completed.
Deleting expired sessions...21 completed.

No other applications are running at the time, and I'm not using the computer.

This has just been a recent thing (last week) , but I've not installed ny new versions of any major software.

Any help appreciated
Thanks!

This is something that macOS's terminal prints. I don't know why it decides to logout in this case.

Thanks for clearing that up Vladimir. It's really weird, only happens a few times ever, despite leaving the machine on to render for long periods. I restarted the render, and came down this morning, and it was all fine

I'll do some investigating.....

Hey, Peepo

Thank you for the feedback. May I ask you what type of image sampler you've been used?

Cheers,
