Having just updated to 4.3.0 just a moment ago, I thought I''d test things out before deploying the updated app. The app for which I''m using Unicorn seems to work fine, however I am seeing some odd errors in the logs that I''ve not hitherto seen and I''m not entirely sure of how to interpret them or to find out more of what may actually be going on. This is running with rails 3.1.4. There are many variations for different files of the following error: 13:38:27 web.1 | Served asset /lofslidernews/lofslidernews_index.js - 304 Not Modified (5ms) 13:38:27 web.1 | 124.253.77.245 - - [27/Apr/2012 13:38:27] "GET /assets/lofslidernews/lofslidernews_index.js?body=1 HTTP/1.1" 304 - 0.0788 13:38:27 web.1 | E, [2012-04-27T13:38:27.179177 #58563] ERROR -- : app error: Socket is not connected (Errno::ENOTCONN) 13:38:27 web.1 | E, [2012-04-27T13:38:27.179373 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/lib/unicorn/http_server.rb:539:in `shutdown'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.179553 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/lib/unicorn/http_server.rb:539:in `process_client'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.179719 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/lib/unicorn/http_server.rb:605:in `worker_loop'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.179881 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/lib/unicorn/http_server.rb:487:in `spawn_missing_workers'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.180048 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/lib/unicorn/http_server.rb:137:in `start'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.180161 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/gems/unicorn-4.3.0/bin/unicorn:121:in `<top (required)>'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.180290 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/bin/unicorn:19:in `load'' 13:38:27 web.1 | E, [2012-04-27T13:38:27.180425 #58563] ERROR -- : /Users/username/.rvm/gems/ruby-1.9.3-p125 at all/bin/unicorn:19:in `<main>'' Would appreciate any help in isolating what may be the issue here. -George
