DR Nodes not rendering.

[Macker]

Hey guys,

Our render nodes won't render. Why they won't render I do not know, they appear to load the scene into ram up to roughly 700mb then stop - a few minutes later the VRay log shows them as not responding and they restart. This continues to happen and neither node ever contribute any render buckets to the render.

Screenshots attached. The ones showing the task managers are remote sessions on the nodes.



We spent the morning re-setting up the network connections on them to rule out any connection problems.

Hi,

Can you post the log file from one of the render slaves?

Make sure that all machines have same V-Ray version installed.
Also try to enable the option "Check for missing files".

As is always the way in this office; the problem has fixed itself for no apparent reason. My bet is our IT guy f*cking with the network, as usual.

Thanks for the update.

Feel free to contact us if it appears again.

It's happened again. This is the VRay Log from one of the nodes:

I can't see why it can't obtain a license. We have 3 seperate license servers, and I can ping all of them from the node.

Crisis averted. For whatever reason (windows update, perhaps?) the firewalls on the workstations had been turned on.

Glad to hear that you have found the issue.
