Hi,

I have exactly the same problem on both of my slave machines. It was ok till switching to Corona 7.1 (before I was using Corona 6).

Slaves are on different windows versions (10 and 7), the same problem on both machines. For sure in my case it's not related to uploading render data to master.

Hi,

I think this might be a slightly different issue, as from your screenshot I can see that your CPU usage is dropping at regular intervals. I think this is due to an issue with the bucket rendering which we introduced in v7. I have a workaround for this, in the development options there is a box for string variables. You can disable the bucket rendering by adding the following into that box, by doing this you will ensure that the buckets don't kick in at all and you won't get this drop in CPU usage.

You have to first enable the development rollout, instructions on this are here: https://support.corona-renderer.com/hc/en-us/articles/4402367677713-How-to-enable-the-Development-Experimental-stuff-rollout-

Just a note, this will NOT fix the DR issue which was reported in this task originally. We are working on a seperate fix for this.
