Howdy, I’m getting an error message when trying to run one of my rails apps, which seems to have started after updating to 10.5.3. mattdaw-2:v1.5\_patch mdaw$ mongrel\_rails start \*\* Starting Mongrel listening at 0.0.0.0:3000 \*\* Starting Rails with development environment… /usr/local/ruby-patched/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/…/ lib/mongrel/tcphack.rb:12:in `initialize_without_backlog': getaddrinfo: nodename nor servname provided, or not known (SocketError) from /usr/local/ruby-patched/lib/ruby/gems/1.8/gems/ mongrel-1.1.5/bin/../lib/mongrel/tcphack.rb:12:in`initialize’ from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:865:in `open' from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:865:in`open\_server’ from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:759:in `open_server' from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:757:in`each’ from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:757:in `open_server' from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:1339:in`initialize’ from /usr/local/ruby-patched/lib/ruby/1.8/drb/drb.rb:1627:in `new' ... 29 levels... from /usr/local/ruby-patched/lib/ruby/gems/1.8/gems/ mongrel-1.1.5/bin/../lib/mongrel/command.rb:212:in`run’ from /usr/local/ruby-patched/lib/ruby/gems/1.8/gems/ mongrel-1.1.5/bin/mongrel\_rails:281 from /usr/local/ruby/bin/mongrel\_rails:19:in `load’ from /usr/local/ruby/bin/mongrel\_rails:19 I’m running ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-darwin9.2.2] which I compiled myself, but another member of my team is using stock ruby from leopard and is getting the same behavior on this one application. Any idea what could cause this? Thanks! Matt ---

I’m using an older version of backgroundrb, and on line 67 of vendor/plugins/backgroundrb/lib/backgroundrb.rb it calls DRb.start\_service(‘druby://localhost:0’). I changed that to DRb.start\_service(nil), which finds the first open port, and it starts up. I haven’t tested this at all, let alone in a production environment, but I will have in a few days. I’d be interested to know if this is all it takes to solve your problem too. ---

Hi Woody, thanks, that fixed it for me. That explains the difference in my app, the newer branches are on an up to date backgroundrb, while the broken one is still on an ancient one. Matt ---
