Hi everyone, I just recently added the facebooker plugin into the vendor/plugin, but have not really used it yet on the staging server. However, it seems that every once in a while I’ll run into an error like this: A SystemStackError occurred in application#index: stack level too deep [RAILS\_ROOT]/vendor/plugins/facebooker/lib/facebooker/rails/routing.rb: 10:in `extract\_request\_environment\_without\_facebooker’ [RAILS\_ROOT]/vendor/plugins/facebooker/lib/facebooker/rails/routing.rb: 10:in `extract_request_environment_without_facebooker' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/rails/routing.rb: 10:in`extract\_request\_environment’ /opt/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action\_controller/ routing.rb:1424:in `recognize' /opt/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/ dispatcher.rb:170:in`handle\_request’ /opt/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action\_controller/ dispatcher.rb:115:in `dispatch' /opt/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/ dispatcher.rb:126:in`dispatch\_cgi’ /opt/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action\_controller/ dispatcher.rb:9:in `dispatch' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/rails.rb:76:in`process’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/rails.rb:74:in `synchronize' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/rails.rb:74:in`process’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:159:in `process_client' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:158:in`each’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:158:in `process_client' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:285:in`run’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:285:in `initialize' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:285:in`new’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:285:in `run' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:268:in`initialize’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:268:in `new' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel.rb:268:in`run’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/configurator.rb: 282:in `run' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/configurator.rb: 281:in`each’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/configurator.rb: 281:in `run' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/bin/mongrel_rails:128:in`run’ /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/lib/mongrel/command.rb: 212:in `run' /opt/lib/ruby/gems/1.8/gems/mongrel-1.1.4/bin/mongrel_rails:281 /opt/bin/mongrel_rails:19:in`load’ /opt/bin/mongrel\_rails:19 I’m not sure what would be the first step in debugging this as it does not seem to happen everytime but often enough and only on the staging server as opposed to the development machines. Does anyone have an idea on what could be going on here? Is it a conflict with another plugin that might have also overridden extract\_request\_environment? Thanks in advance.
