Hello there, I seem to have a problem with unix-sockets, and cannot see many people with the same situation when googling.
The problem is when upgrading (USR2 + QUIT) our applications. I get the following error very frequently but not always. E, [2012-06-21T11:40:46.386486 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) E, [2012-06-21T11:40:46.386669 #29401] ERROR -- : retrying in 0.5 seconds (4 tries left) E, [2012-06-21T11:40:46.887724 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) E, [2012-06-21T11:40:46.887832 #29401] ERROR -- : retrying in 0.5 seconds (3 tries left) E, [2012-06-21T11:40:47.388813 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) E, [2012-06-21T11:40:47.388894 #29401] ERROR -- : retrying in 0.5 seconds (2 tries left) E, [2012-06-21T11:40:47.889878 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) E, [2012-06-21T11:40:47.889957 #29401] ERROR -- : retrying in 0.5 seconds (1 tries left) E, [2012-06-21T11:40:48.390939 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) E, [2012-06-21T11:40:48.391020 #29401] ERROR -- : retrying in 0.5 seconds (0 tries left) E, [2012-06-21T11:40:48.892002 #29401] ERROR -- : adding listener failed addr=/tmp/unicorn.app.sock (in use) /var/www/app/staging/shared/bundle/ruby/1.8/gems/unicorn-4.3.0/lib/unicorn/socket_helper.rb:140:in `initialize': Address already in use - /tmp/unicorn.app.sock (Errno::EADDRINUSE) ...and the only way around that I know is stoping and starting the app, even in production. We have preload_app => true, and ONLY listening on unix-sockets, no TCP-sockets. The only solution I can think of would we switching to TCP, but would there be a reason on doing such ? Is this happening to any body else ? and would you know a possible solution ? Thanks very much in advance !
