Hello all, I am trying out squid with SMP. I am using squid version 3.3.4. Squid works fine without "workers" directive i.e. without SMP. For SMP, all I do is add is these two lines on top of squid.conf, rest of squid.conf is exactly same. workers 2 cpu_affinity_map process_numbers=1,2 cores=1,2 After this I see these lines in cache.log every 12-15 seconds. (sometimes kid1 sometimes kid2) 2013/05/13 20:36:21 kid2| varyEvaluateMatch: Oops. Not a Vary object on second attempt, 'http://www.espncricinfo.com/netstorage/598060.html' 'accept-encoding="gzip,%20deflate"' 2013/05/13 20:36:21 kid2| clientProcessHit: Vary object loop! Squid works fine though. (from just 5-10minutes testing) Any idea what is the issue? Can it make squid unstable? Or its just a warning of some sort which can be ignored safely? Thanks and regards, Amm.
