Since you can reproduce this, I suggest collecting ALL,9 log for the
stuck master transaction:

http://wiki.squid-cache.org/SquidFaq/BugReporting#Debugging_a_single_transaction

If collecting a debugging trace is impossible for some reason, then
collect the corresponding TCP packets on the Squid to origin server link
and post actual packets (not screenshots of packet summaries) from both
connections. The debugging trace will most likely have the answer. The
packet trace might have the answer.

You may need to change user credentials for this test or after posting
the details requested above.


Cheers,

Alex.
