The log does not tell us much except that it was a cache MISS and that a
206 was delivered to the client.

Also, note that the duration column matters a lot. It indicates that the
second of those entries was started and still ntot yet completed when
the first happened.


A "debug_options 11,2" cache.log trace with the full HTTP message
headers to/from client and to/from server for these is neeed to see what
exactly is going on at the traffic level.

A deeper (ALL,5) cache.log trace might be needed to see what is causing
that traffic level messaging to happen if its not obvious from the 11,2
details.
