Issues with render nodes dropping

[bob_grow]

Hey all,

We are having issues with our in-house render farm, specifically with multiple nodes not being used and when we check, they say they are at 0% CPU usage. It is happening to a bit over half of our 16 render nodes, and we are unsure why. When we run the vraydr_check on the nodes, they display as “ready" while the functioning nodes say “busy”, but the “ready” nodes do not kick on when we start a render.

Wondering if anyone has had this issue before and can give us some insight. Thanks!

3D/Host Platform: Maya 2018
Product Version: V-Ray 4.12.02
OS: Windows 10

Edit: Found the problem. Some of our V-Ray licenses had expired a few days ago and we only realized yesterday.

Hello there,

Is it possible for you to check if this same problem is reproducable with a more recent V-Ray build such as 43003 or V-Ray 5.0?
There is a possibility that the problem has been fixed there already.
Also if you can send us a log from the poblematic scene with the flag -verboseLevel=4 (when you start the server), for our developers to have look into it.

Kind Regards,
Dimitrina
