Thanks for the input/comment - we are running v7.7 - I came across that link when I first noticed there was a problem and the list of vulnerabilities wasn't changing/updating.
I've tried that several times, and that's when I noticed in the logs that it seems like it's "skipping" the import of the files, so nothing new is being added - not sure why that's happening - it seems to identify the files in the correct path and goes through the motions, but doesn't update anything -
Any other suggestions for me to try?
If anybody happens to have this issue:
I just talked to a guy at Solarwinds support and he said this is a known issue. It should be fixed with the next NCM release (v7.8).
