I'm not sure if the issue is coming from Corona 3 or Deadline.
If we use a light mix and submit a DR render using Deadline the render freezes intermittently during rendering.
And once it have finished it hangs before denoising. It sometimes comes right after 20-30mins.
If we remove the light mix no issues.

Something went wrong with the lightmix. I am experiencing some serious issues as well.
First of all, after I adjust the lights in the lightmix and press the ">scene" button, the lights in my scene changes completely.
If the lightmix is on and I render using the DR servers (not Deadline, just the built in DR servers) it takes ages to start the render (~20 minutes) and when I want to stop the render my Max just hangs up, in most of the time the only thing what I can do just to kill the 3DS Max process in the task manager. I waited more than 30 minutes and nothing.
I am going to upload the scene for you guys with some examples as well. It's WIP, so it looks how it looks.
It's on your Dropbox "corona_issues.zip"

We are now experiencing problems with scenes that don't have any light mix.
The DR servers are only kicking in on few machines.
We tried turning of Displacement with no luck.

This is the log from one of the DR servers:

2018/12/05 11:39:48 INF: [07124] [08884] CORONA : Calculating displacement
Seems to be stuck on Displacement. Even through all displacement is off.
-
After monitoring it for a couple of days here is my observation:
When using DR servers it freezes on and off when rendering.
After completing the main render before denoise the render freezes waiting for servers.
If we remove the DR servers the render starts denoise and completes.
We some times get this error: "Sending sampling mask to slaves timed out. Try to increase synchronization time or decrease maximum pixels per transfer."
Should we submit a bug?

Hi guys and sorry for the delay.
Alex - I have contacted you through our support portal (using the email address you provided here on the forum). Please let me know if you can't find my message.
Bcgi - I am about to send you an email as well.
-
Thx Maru.
Just a quick update.
We rolled back to Corona 2 as we just couldn't go forward with Corona 3.
Back on Corona 2 and everything is working fine with Deadline.
We have some issues with scenes going back to corona 2 but once we merge into a new scene no issues.

I came across this thread from a Google search, but we're running into a similar issue on our Deadline render farm. Same unknown ClassID.

Was there any findings as to what this class is? We are actually using V-Ray, but as far as I can tell these are not V-Ray-specific classes. In our case we are not using DR.
Thanks!

We had many problems with Corona 3 and deadline.
After installing version 4 the problems have disappeared.
Also installed latest version of Deadline.
We installed Corona 4 and made sure each render node could render with manual DR Server.
Also completed removed deadline & corona before installing update.
-
And now we have the problem again with Corona 4 and Deadline 10.0.27.2.
Sigh...

I'm getting the following errors on the slaves.

Seems to send some and then not.
I'm going to try rendering on the slaves with out Deadline.

So tried reducing the "Max pixels to transfer at once" to 1000000
And tried running the Drserver manually this seems to help.
Could this be a network throughput problem?
