perfSONAR User Q&A and Other Discussion

[Michael Johnson <>]

Hi Charley,

I've tried to reproduce this on a couple other hosts, and I'm not having any 
luck. Can you provide a bit more detail as to what is going on?

When you say your browser "hangs," or "crashes" whare are you seeing? Does it stop responding entirely? Do you see a "loading" indicator that never goes away? Does the entire browser window go away? Some other behavior? 

If possible, could you provide the following?
- A screenshot
- A list of errors that show up if you go to Tools -> Web Developer -> Web 
console (if you see these, you can ignore them):
"Warning: Each child in an array or iterator should have a unique "key" prop. 
Check the render method of `chart1`."
OR
"Warning: Failed propType: Invalid prop `children` supplied to `ChartContainer`. 
Check the render method of `chart1`."

Do you see this in other browsers?

Thanks,
Michael
