I’m trying to use the Ferret DRB server to avoid concurrency issues when using multiple mongrels. I can successfully add and edit data on my index via the DRB server, however, when I search the index, I get the following error: DRb::DRbConnError (DRb::DRbServerNotFound): /usr/lib/ruby/1.8/drb/drb.rb:1647:in `current_server' /usr/lib/ruby/1.8/drb/drb.rb:1709:in`to\_id’ /usr/lib/ruby/1.8/drb/drb.rb:1045:in `initialize' /usr/lib/ruby/1.8/drb/drb.rb:639:in`make\_proxy’ /usr/lib/ruby/1.8/drb/drb.rb:556:in `dump' /usr/lib/ruby/1.8/drb/drb.rb:600:in`send\_request’ /usr/lib/ruby/1.8/drb/drb.rb:599:in `send_request' /usr/lib/ruby/1.8/drb/drb.rb:903:in`send\_request’ /usr/lib/ruby/1.8/drb/drb.rb:1191:in `send_message' /usr/lib/ruby/1.8/drb/drb.rb:1083:in`method\_missing’ /usr/lib/ruby/1.8/drb/drb.rb:1167:in `open' /usr/lib/ruby/1.8/drb/drb.rb:1082:in`method\_missing’ /usr/lib/ruby/1.8/drb/drb.rb:1100:in `with_friend' /usr/lib/ruby/1.8/drb/drb.rb:1081:in`method\_missing’ /vendor/plugins/acts\_as\_ferret/lib/remote\_index.rb:20:in `find_id_by_contents' /vendor/plugins/acts_as_ferret/lib/class_methods.rb:120:in`find\_id\_by\_contents’ /vendor/plugins/acts\_as\_ferret/lib/class\_methods.rb:176:in `ar_find_by_contents' /vendor/plugins/acts_as_ferret/lib/class_methods.rb:170:in`find\_records\_lazy\_or\_not’ /vendor/plugins/acts\_as\_ferret/lib/class\_methods.rb:86:in `find_by_contents' /app/models/article.rb:104:in`full\_text\_search’ /app/controllers/search\_controller.rb:93:in `index' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/base.rb:1095:in`perform\_action\_without\_filters’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/filters.rb:632:in `call_filter' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/filters.rb:619:in`perform\_action\_without\_benchmark’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/benchmarking.rb:66:in `perform_action_without_rescue' /usr/lib/ruby/1.8/benchmark.rb:293:in`measure’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/benchmarking.rb:66:in `perform_action_without_rescue' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/rescue.rb:83:in`perform\_action’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/base.rb:430:in `process_without_filters' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/filters.rb:624:in`process\_without\_session\_management\_support’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/session\_management.rb:114:in `process' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/base.rb:330:in`process’ /usr/lib/ruby/gems/1.8/gems/rails-1.2.3/lib/dispatcher.rb:41:in `dispatch' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/rails.rb:78:in`process’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/rails.rb:76:in `process' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:618:in`process\_client’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:617:in `process_client' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:736:in`run’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:736:in `run' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:720:in`run’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:271:in `run' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:270:in`run’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel\_rails:127:in `run' /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/command.rb:211:in`run’ /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel\_rails:243 /usr/bin/mongrel\_rails:16 * * * When I’m adding/editing data in the index, my ferret\_server.log file shows the following: #method\_missing(:add, [“Article”, {:synopsis=\>“Analysis and Projections”, :status=\>1, :player\_names=\>"", :team\_names=\>"", :publisher=\>"", :title=\>“Article Title”, :db\_state=\>0, :id=\>1, :article\_published\_date=\>1189115220}]) #method\_missing(:add, [“Article”, {:synopsis=\>“Analysis and Projections”, :status=\>1, :player\_names=\>"", :team\_names=\>"", :publisher=\>"", :title=\>“Article Title 1”, :db\_state=\>0, :id=\>1, :article\_published\_date=\>1189115220}]) #method\_missing(:add, [“Player”, {:last\_name=\>“Smith”, :first\_name=\>“Walter”, :db\_state=\>0, :id=\>1}]) #method\_missing(:add, [“Team”, {:name=\>“Kalispell HS”, :db\_state=\>0, :id=\>13}]) * * * I’m running the following environment: Linux version 2.6.16.29-xen\_3.0.3.0 mongrel (1.0.1) mongrel\_cluster (1.0.2, 0.2.1) ferret (0.11.4) acts\_as\_ferret stable plugin (as of 9/7/2007) I have no problem running this application on my local development environment… and I had no problems running in this hosting environment before I started using Ferret DRB. Here are some example sorts and/or filters I’m using in my searches (not sure if this matters to Ferret DRB or not): Ferret::Search::SortField.new(:article\_published\_date, :reverse =\> true) Ferret::Search::Sort.new([Ferret::Search::SortField::SCORE, date\_sort]) Ferret::Search::RangeQuery.new(:article\_published\_date, :\>= =\> UserSystem::APP\_DEFAULTS[:days\_for\_new].days.ago.utc.to\_i.to\_s, :\<= =\> Time.now.utc.to\_i.to\_s) Ferret::Search::Sort.new([Ferret::Search::SortField.new(:article\_published\_date, :reverse =\> true)]) Any ideas why my searches wouldn’t be working?
