JeLuF recently set up the Wikimedia servers to send their syslogs to zwinger,
and we noticed that from each of the squids, messages like the following are
regularly appearing in /var/log/messages:
Jun 15 11:00:53 coronelli squid[1192]: varyEvaluateMatch: Oops. Not a Vary
match on second attempt, 'http://en.wikipedia.org/wiki/Loop_quantum_grav
ity' 'accept-encoding="gzip,%20deflate",
cookie="enwikiSession%3dd01e31dd136539b2bdd41027d84368c8"'
Jun 15 11:00:55 coronelli squid[1192]: clientProcessHit: Vary object loop!
I've switched the messages off for now by adding "debug_options 33,0" to
squid.conf on each squid, because they were repetitive and drowning out
anything else in the log. Gabriel, do you have any idea what's wrong here?
