req.text on line 217 of ness6rest.py was hanging with high CPU usage when calling download_scan and returning a 61MB csv scan.
Here is an example trace when I hit Ctrl-C:

I changed line 217 to read "else:" and it is functional now, but i'm not certain if other features needed the previous logic "elif not req.text:", though it would seem to be mostly implied that it is not req.text if it already failed the first if condition.
The code section now reads:
if not download and req.text:
self.res = req.json()
else:
self.res = {}
tenable
