If you can put together a full Sandcastle example reproducing this it’ll help a lot. Just go to Sandcastle (https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/), create the example and then click “Share” and paste the link you get here.

What kind of data do you have running in your application? The closest thing I found is this error coming up when using big KML:

Does it happen on startup only or while you’re using the application? Or while loading new geometry in?
