Something else is going on which is not visible in the details you have
shown.

 - is the TCP connection containing a message pipeline?
 if so the data and FIN may be related to a previous response message in
that pipeline.

 - are other refresh patterns being used (probably yes) ?
  - what are they? (before and after the change)

 - what did your cache.log have to say at the time of the connection
termination? (may need debug level 2 or 5 enabled)


Also, you were using override-* and ignore-* settings in that
refresh_pattern that are not necessary for the Debian/Ubuntu servers.

 At best they will be doing nothing to these responses (ie
ignore-no-store, ignore-private do nothing to Debian/Ubuntu responses).

 Some will be causing *worse* caching service from the proxy.
override-lastmod with your small [84 day] expiry vastly reduces the
_years_ these objects can actually be cached for, and prevents IMS
revalidation being used to determine changes properly and store
un-changed things longer. NP: Debian/Ubuntu official repositories do
fully support IMS revalidation.
