Do you have any other requests in your logs which could be taking a long time and hogging workers, but not high enough to trigger the unicorn kill timeout. (enable $request_time in nginx access logs if you haven't already) Is this with Unix or TCP sockets? If it's over a LAN, maybe there's still a bad switch/port/cable somewhere (that happens often to me). With Unix sockets, I don't recall encountering recent problems under Linux. Which OS are you running? I hit several TCP bugs in the early 3.7 Linux kernels, too... _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
