Hello everyone! I have a problem...Explaning from the begining.
I have a project of exterior, which counts for now 3.5 million poligons, all other hi-poly models in proxy. Less then a week ago, i've started to have problem with rendering, my scene didnt want to do interactive rendering, render was super slow etc. I thought it was problem that i had lots of my textures etc on harddrive, so i did asset and put it to my ssd... it didnt help... i can say that corona took all of my 32GB of RAM send me errors etc, in the middle of the render my computer just freeze at all, everything stop work and i"ve needed to reboot it from the button, and it was render of a picture 1280px by big side. Yesterday i tried to do render one more time, in the beggining, after 2 hours of counting GI, it started to work, so i left it for the night, hope it will be somehow half-ready by the morning, but after 14 hours of rendering i see, Noise level the same, everything the same!!! So render time was going but render was not moving any further at all! ((
Otherwise before I have used much bigger scenes, and i didnt have such a problem at all...at this time I've used Intel core i5 6500k, 32GB RAM.
For me this project very urgent, so I've changed my computer today to a new one, I use now: AMD Ryzen 7 1700x eight core processor 3.40 GHz, 64 GB RAM.
I've tried to do render on new PC, so what i see:
Interactive-doesnt work at all, computer just buffering without any progress
Render itself- woohoo! i dont get error about my low ram, cuz Corona took it almost all 64GB, GI works fast, but as soon as render starts, after about 10 passes, but computer just crush...
I really dont know what to do, may be someone had such a problem and can help me...
Thank you.

The problematic scene was set to our support. The issue with RAM usage is simply because it is an extremely heavy scene with a lot of detailed objects. It simply did not fit into 32GB of RAM, and that is why upgrading to 64GB helped. The solution here would be to optimize the scene, mainly by using lower quality assets, and utilizing instancing as much as possible. Some additional tips can be found here: https://coronarenderer.freshdesk.com/support/solutions/articles/12000023310
Extremely slow or completely halted rendering is expected when running out of RAM.

We are looking into the crashes/other issues right now.
