I'm trying to figure out exactly how the knowledge base works. Below are my

and have a complete report.
That sounds more or less right. The only quibble I have involves "a
complete report". I'd expect the report would only contain information
obtained from when you resumed the scan, not anything that was obtain
before the scan was terminated half-way through. You should be able to
verify this with the help of nessusd.messages.
If I launch another scan on the same hosts before the kb_max_age expires,
the scan doest not run. I end up having a blank output file.
That's because you're using the KB and you have the four kb_dont_replay*
settings enabled. [Actually, you might still get a report if you add
*new* plugins to the server and those generate a report.]
Is there any documentation that
explains how this works?
There's a full chapter about the Knowledge Base in "Nessus Network
Auditing". Or you could refer to edgeos Security's Nessus Knowledge
Base, <http://www.edgeos.com/nessuskb/> (and ignore the link to
<http://www.nessus.org/doc/kb_saving.html>, which is no longer accurate).
