When I try to upload a file using the file_field_tag I get the following exception (top 10 lines in the stack shown):
/!\ FAILSAFE /!\ Tue Dec 09 17:11:12 -0500 2008 Status: 500 Internal Server Error End of file reached /usr/local/lib/jruby-1.1.5/lib/ruby/1.8/pstore.rb:355:in `load' /usr/local/lib/jruby-1.1.5/lib/ruby/1.8/pstore.rb:355:in `load' /usr/local/lib/jruby-1.1.5/lib/ruby/1.8/pstore.rb:310:in `transaction' /usr/local/lib/jruby-1.1.5/lib/ruby/gems/1.8/gems/actionpack-2.2.2/ lib/action_controller/cgi_ext/session.rb:48:in `initialize' /usr/local/lib/jruby-1.1.5/lib/ruby/1.8/cgi/session.rb:273:in `initialize' /usr/local/lib/jruby-1.1.5/lib/ruby/gems/1.8/gems/actionpack-2.2.2/ lib/action_controller/cgi_ext/session.rb:19:in `initialize' /usr/local/lib/jruby-1.1.5/lib/ruby/gems/1.8/gems/actionpack-2.2.2/ lib/action_controller/cgi_process.rb:94:in `session' /usr/local/lib/jruby-1.1.5/lib/ruby/gems/1.8/gems/actionpack-2.2.2/ lib/action_controller/cgi_process.rb:130:in `stale_session_check!' /usr/local/lib/jruby-1.1.5/lib/ruby/gems/1.8/gems/actionpack-2.2.2/ lib/action_controller/cgi_process.rb:78:in `session'
The problem appears to be in the temp session file in RAILS/tmp/ session; if I try to load it using Marshal::load(filename) I get a "Marshal data too short" error. I can store other values in the session without any problems. Any ideas on what I can do to get around this?
