Highend Demo Import taking 3+ hours so far

I kicked off the full highend demo import about 3 hours ago after making all of the necessary configuration changes to memory, timeout, etc.. The import has been running for quite sometime.. no errors have appeared but it says it may take a few minutes to run.. it’s been running for hours now. How do I know if it’s hung or completed? If it is hung, how do I restart?

Thanks in advance,
