array buffer allocation failed

1. A concise explanation of the problem you're experiencing.

This mistake will happen occasionally.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

          availability: new Cesium.TimeIntervalCollection([new Cesium.TimeInterval({
            start: start,
            stop: end
          position: satellitePosition,
          orientation: new Cesium.VelocityOrientationProperty(satellitePosition),
          label: {
            font: '18px Helvetica',
            fillColor: 'red',
            outlineColor: 'red',
            style: Cesium.LabelStyle.FILL_AND_OUTLINE,
          path: {
            show: true,
            width: 3

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you're using, your operating system and browser.

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?
