net::ERR_INSUFFICIENT_RESOURCES errors

Hi,

I'm experiencing "net::ERR_INSUFFICIENT_RESOURCES" errors while loading high resolution images on Neuroglancer. Initially, I configured 10,000 for "Concurrent chunk requests" and this value seems to have caused the errors. My internet connection is somewhere in 67Mbps~70Mbps (WiFi). After adjusting to 100 concurrent chunk requests, I stop seeing the errors. Could someone advise how to configure with appropriate numbers?

Also for the GPU memory limit and System memory limit, how do I know that I'm using the full capacity? I use macOS and looking at the Activity Monitor specifically for Chrome (top two in the screenshot). 3.55GB and 2.14GB. Does it mean I've used up all the available resources for Neuroglancer?

Thank you for your guidance!
