My guess is that one of these two things happen:

- For some reason your DNS server stopped answering our queries and
thus we had to stop with that error
- For some reason, w3af was trying to request a URL with a
non-existing domain, and failed when trying to perform requests to it

A couple of things you can do:

- Set the target domain in your /etc/hosts
- Send us more detailed logs (maybe the output of running: grep "Name
or service not known" output-w3af.txt -C150)

One important question to ask is... are you able to reproduce this
every time you scan that website?
