Is this happening with any .hip file? Could you share some scene?
What is the exact V-Ray for Houdini build are you using?

> ubuntu22.04 and rocklinux8.7

So, is render node ubuntu22.04 or rocklinux8.7?

7

Want to confirm that we have received the scene and the V-Ray build in the ticket and are discussing them.

plese help

> not all machines, older machines only,

What does “older” mean?
Is there a way to figure out which exact machines are crashing and how are they different from machines that are not crashing?
Is result image file written or crashes during rendering?
Are you rendering with Standalone or hbatch/hython?

20

by old I mean machines with Intel Xeon CPU E5-2600 Windows 10 64-bit

they randomly show an error with about a 10% chance. I could not find any differences because the machines that errored out could render normally later in the same job.

The image is written successfully; I actually stared at the folder and waited for the error. Once it appeared, I paused the Deadline job, and the image was there. However, the error triggers a requeue of the frame, which wastes a lot of time.

I am rendering using Hython and the Deadline Houdini plugin.

Other machines with Intel Xeon CPU E5-2698 V4 and Windows 10 64-bit never have this problem.

All machines do not have GPUs and cannot open the Houdini interface at all, but they used to render just fine.

The problem first appeared around July of this year, after some V-Ray or Houdini update; I can’t remember which. Full error details are attached:​
