Ever since I updated rails to 2.3.8, script/server exits right after it starts. Here's the output

=> Ctrl-C to shutdown server [2010-05-29 18:14:58] INFO WEBrick 1.3.1 [2010-05-29 18:14:58] INFO ruby 1.9.1 (2009-01-30) [i686-linux] [2010-05-29 18:14:58] WARN TCPServer Error: Address already in use - bind(2) Exiting /usr/local/lib/ruby/1.9.1/webrick/utils.rb:73:in `initialize': Address already in use - bind(2) (Errno::EADDRINUSE)   from /usr/local/lib/ruby/1.9.1/webrick/utils.rb:73:in `new'   from /usr/local/lib/ruby/1.9.1/webrick/utils.rb:73:in `block in create_listeners'   from /usr/local/lib/ruby/1.9.1/webrick/utils.rb:70:in `each'   from /usr/local/lib/ruby/1.9.1/webrick/utils.rb:70:in `create_listeners'   from /usr/local/lib/ruby/1.9.1/webrick/server.rb:74:in `listen'   from /usr/local/lib/ruby/1.9.1/webrick/server.rb:62:in `initialize'   from /usr/local/lib/ruby/1.9.1/webrick/httpserver.rb:24:in `initialize'   from /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.0.1/lib/rack/handler/webrick.rb:10:in `new'   from /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.0.1/lib/rack/handler/webrick.rb:10:in `run'   from /usr/local/lib/ruby/gems/1.9.1/gems/rails-2.3.5/lib/commands/server.rb:111:in `<top (required)>'   from script/server:3:in `require'   from script/server:3:in `<main>'

I think the problem is with bind, but I have no idea what to do with it. Thanks in advance

It means exactly what it says: you have another process, probably a previous instance of webrick, already running on the port that your new instance is trying to bind to.

Find it and kill it.

`man netstat` might be of help if you have trouble figuring out which process id is responsible.

HTH,
